For the development and validation of systems for autonomous vehicle management, real traffic scenarios are usually simulated and tested in the laboratory. Since pre-processing is carried out directly in the sensor front end with modern radar sensors, this can result in a serious gap in coverage during the testing and validation of object detection. In addition, the optimization of algorithms for testing in real traffic is very complex and seldom reliable.

The DP²4R Gigabit Data logger collects raw radar signals between the sensor and preprocessing. The stored signals can then be fed back via the same interface. This allows real traffic situations to be replicated repeatedly in the laboratory and to optimize the processing chain of radar signals. The testing and validation of radar signal processing can be moved from the road to the laboratory. This saves time and allows the reliability of the data processing to be documented.

The special approach of the DP²4R data logger is to read raw data by means of a data head directly coupled to the radar sensor, store it and later feed it back in the laboratory. This requires a high data rate of more than 300Mbit / s per sensor, which is why these data can not be transferred via the system bus.

For practical aspects of data analysis, apart from raw sensor data, other context-specific data like pictures from a camera and GPS position data can be recorded with synchronous precision.

The so-called „head unit“ is based on a standardized unit which is specifically tailored to each sensor in order to enable safe and interference-free signal scanning as well as re-injection of the raw data. The sampled information is transmitted together with a time stamp via an internal interface to the central unit.

The central unit consists of a car PC with a special insert card. Up to four head units with a cable length of 7m can be connected to it. An even larger number of head units can be connected via a second or third card slot.

For data storage, there are several „hot-plugged“ SSD drives, which can be used to record data of any length by changing the media during recording. Other arrangements of storage media, such as aggregated RAID systems, can also be easily implemented. The entire hardware has been designed for the environmental conditions within the vehicle.

The system is controlled via Ethernet with a machine-readable xhtml interface or a web browser. The external data transfer is carried out via Gigabit Ethernet or through media change.

The concept has been designed for future extension with additional sensors with a larger number of antennas and higher radar frequency.

35 years of Palas GmbH:

Pioneer and global market leader with profound expertise of nanoparticles

35 years of Palas GmbH:

Test bench presentation in Utrecht 1985 (Source: Palas GmbH)

When Leander Moelter founded Palas GmbH in 1983, aerosol technology was still in its infancy in Germany. And yet he had the vision of developing a profitable business based on „measuring and generating particles“. 35 years later, Palas® holds not only 74 patent applications but is also the worldwide market leader in the field of optical aerosol spectrometers and filter testing systems.

Today, one would describe it as a start-up with which Leander Moelter began his exemplary career 35 years ago as an aerosol technology specialist in a residential building in Eggenstein-Leopoldshafen, Baden. In 1979, he had successfully completed his studies in precision engineering with a focus on communications engineering at the University of Applied Sciences of Karlsruhe, and he was already responsible for development and sales as a co-partner in a manufacturer of measuring equipment for laser Doppler anemometers. He was also a member of the VDI working group „Measurement of Particles“. However, the aerosol generation systems described in the VDI guidelines were mostly used as laboratory setups only, and the sole manufacturer of suitable measuring equipment was located in the U.S..

Although aerosol technology with fine dust measurement and air quality monitoring, things that are so self-evident today, was an area that was hardly noticed in Germany and Europe at that time, Leander Moelter recognized this as a market opportunity and discussed the plan to found a company to measure particles together with his brother Wolfgang and Fritz Munzinger. The resulting business concept convinced even the highest committees: Moelter emerged as the third winner out of more than 1,000 participants in the „Ways to self-employment“ competition organized by the Capital magazine.

September 12, 1983 was the birth of the now so successful Palas GmbH, which was to become the worldwide market leader in aerosol production, dilution and particle measurement technology in the years to come.

One of the success factors of the young Palas GmbH were the annual scientific platforms on the subject of aerosol technology, which had been established early on. Leander Moelter was also a member of the round table for the founding of Technologiefabrik Karlsruhe, which also included the then Prime Minister of the State of Baden-Wuerttemberg Lothar Spaeth, representatives of the Chamber of Industry and Commerce and the University of Karlsruhe. Just one year later, in the summer of 1984, Palas GmbH moved from the residential building to the newly founded Technologiefabrik, which, from the very beginning, was regarded as an „incubator“ for many later highly successful companies.

Palas® counts

Daily in the media today, but still uncharted territory at that time: Diesel soot emissions. For their accurate measurement and analysis, Palas GmbH developed, together with the renowned Fraunhofer Gesellschaft, a filter photometer, which was followed in 1985 by the first saleable filter media test stand. The system was rightly celebrated as an innovation at the Filtech international trade fair in Utrecht: It was the world’s first measuring technology to evaluate the efficiency of a filter depending on particle size.

As early as 1986, the young Palas GmbH with only three employees developed ten products, such as the RBG and BEG dust feeders. The AGF aerosol generators are used to nebulize liquids, and the VKL dilution systems are used to dilute highly concentrated aerosols.

The installation of a particle counter of Russian origin into a filter test system and the subsequent license agreement with Dr. Umhauer & Prof. Loeffler from the University of Karlsruhe for in-house production at Palas® under the product name Particle Counter Sizer PCS 2000 proved to be particularly visionary.

Smaller, lighter, more accurate

While the first system still weighed 28 kg and required a peripheral zone correction, this was not necessary with the T-iris and fiber optic technology developed as part of the C1 program funded by the State of Baden-Württemberg, which led to the construction of the 2.8 kg light welas® system, a white light aerosol spectrometer, in 2000.

Between 1990 and 2000, the increasingly higher measuring accuracy under extreme conditions such as overpressure, temperatures from -90° to 250°, as well as the higher miniaturization meant a breakthrough in aerosol technology. Today, the smallest device weighing only 200 grams is light as a feather, can be wirelessly controlled and is used in numerous industries.

A leap into digitalization

Entering the digital world, Palas® also revolutionized the aerosol technology when they implemented a digital platform for the welas® system in 2008. This allowed the particle signals to be better analyzed and measured in even higher concentrations.

„Count what is countable, measure what is measurable, and make measurable what is not measurable!“ In accordance with this principle of Galileo Galilei, the development of measurements of the smallest fine dust fractions in the micrometer range (PM10 and PM2.5) finally followed. With the introduction of the Fidas® fine dust measuring instruments (Finedust aerosol spectrometer) Leander Moelter quickly realized that this was the beginning of a completely different category of measuring instruments and global markets: Palas® now entered the new territory of the worldwide increasing environmental measuring technology with completely new target groups, which, however, required internationally recognized certifications and new dimensions of development, production and sales.

Motivation and Innovation Boost through Lean Management

In 2013, together with his new R&D director Dr.-Ing. Maximilian Weiß and a management consultancy, Leander Moelter decided to streamline processes, flatten hierarchies and perform certification compliant with the ISO 9001 quality management system. At the same time, the employees were more closely involved through short communication channels.

Despite the initial skepticism of the workforce towards the new lean management, the program proved to be a complete success: Identification with the company, motivation and inventiveness, resulting in innovations, especially in the development of new nanoparticle and fine dust measuring systems for environmental use, brought Palas® further ahead. The shareholders invested all profits exclusively in development. Expansion and increases in sales led to revenues of five million Euros in 2014, an increase of 26 percent from the previous year.

Today and tomorrow

Today, the Fidas® fine dust measuring systems – highly flexible stationary and mobile devices with the highest measuring accuracy that can also be applied in drones – are, at 50 per cent share, the mainstay of revenues amongst the roughly 150 products of Palas GmbH, which meanwhile grew to 68 employees.

The area of fine dust measurement offers considerable market opportunities in the future. Leander Moelter and Dr.-Ing. Maximilian Weiß, the other managing director of the company have since long recognized that air testing is not limited to outdoor applications only. Looking at the leading Asian countries in this field, interior monitoring in office buildings, schools and other buildings is becoming more and more important, and the demand for highly specialized equipment is increasing.

The subject of fine dust has also reached filter test stands in the meantime, with particle size distribution in the range of 0.3µm to 10µm being adapted even more closely to realistic conditions in future filter development, thus reacting to the real-world requirements of recent years. These new regulations are summarized in the ISO 16890 standard, which Palas® has already started to implement in the filter test benches and offers initial solutions.

A big success factor of Palas GmbH is its wide coverage of many customers and industries: In addition to federal and regional authorities, this includes the areas of automotive, environmental technology, health care and pharmacy, to which Palas GmbH supplies complete systems directly or via experienced local sales partners. In addition, Palas® supports its customers with know-how, seminars and trainings in all matters of aerosol technology and supplies everything from a One-Stop Shop. The company is thus well positioned equipped for the future as a global supplier of aerosol spectrometers and filter test systems.

Since 35 years, Palas GmbH is developing, producing and selling measuring instruments and filter test benches in the fields of aerosol technology and particle measurement. Today, Palas® is one of the international market leaders in numerous product fields. The headquarters are located in Karlsruhe, Baden-Wuerttemberg, and the measuring instruments are used worldwide – currently via a network of sales partners in approx. 50 countries worldwide.

„Unmet Medical Need“ Retinitis pigmentosa: this challenge can only be solved together

RI Forum 2018: International retinal experts discuss retinal implants

"Unmet Medical Need" Retinitis pigmentosa: this challenge can only be solved together

International RI-Forum 2018 with retinal experts from all over Europe (Source: Retina Implant AG)

(Reutlingen / Vienna) – On the fringe of this year’s EURETINA congress that took place in Vienna from 20 to 23 September 2018, retinal experts from all over Europe met for the second international RI-Forum. More than 20 specialists followed the invitation of Retina Implant AG and discussed the topic:

Addressing the Unmet Medical Need of Retinitis pigmentosa (RP): teaming up to pave the way for today`s available methods

The medical challenge of treating the hereditary retinal disease RP is huge and in many cases it leads to blindness. A therapy that heals all forms of this disease is not in sight, despite great efforts and initial success with gene therapy approaches. „It continues to require the combined effort of science, medicine and industry to improve the situation for many RP patients,“ explained Dr. Alfred Stett, Chief Technology Officer of Retina Implant AG that hosted the expert panel. „Our electronic implant is already available to people who are blind from RP – regardless of the genetic cause of retinal disease.“

The Reutlingen-based Retina Implant AG has developed a retinal implant that can partially restore vision in people who have no or only bare light perception due to various forms of degenerative retinal diseases such as RP. Reimbursement is already available in Germany and France. „The subretinal implant is absolutely resilient in terms of function and safety. And it’s available,“ said Professor Florian Gekeler, Medical Director at the Katharinenhospital Stuttgart in Germany.

Professor Robert MacLaren, Professor of Ophthalmology at the University of Oxford UK, is convinced by the implant: „The electronic retinal implant has both light sensitivity and retinal stimulation built into it – hence when placed under the retina it truly replaces the role of photoreceptors, which are the light sensitive cells lost in patients who become blind from retinitis pigmentosa.“

The fact that there are still some challenges to overcome is accepted among all specialists in the group. „We observe that the visual perceptions generated by the implant are steadily improving with regular vision training. This has led us to develop a rehabilitation and training concept that allows patients to progressively train the use of the implant and certain visual abilities,“ explains Dr. Stett.

In addition to questions about rehabilitation, technology and surgery, the clinical experts also discussed in depth the selection of suitable patients. „Some of the most experienced international retinopathy experts have joined this RI-Forum because exchanges and collaboration need to be stepped-up to jointly overcome all barriers to existing therapies – from both patients‘ and physicians‘ perspectives,“ Prof. Gekeler summed up the evening.

About Retina Implant AG
Retina Implant AG researches and develops innovative treatments and high-tech products for people suffering from retinitis pigmentosa (RP). The subretinal RETINA IMPLANT Alpha AMS can help blind patients regain a certain degree of useful sight. The CE-approved microchip is implanted beneath the retina (subretinally) at specialist RI implantation centres.
Transcorneal electrical stimulation (TES treatment) with the RI OkuStim® system offers RP patients with sufficient residual vision the opportunity to slow down the progression of the disease.
The company, based in Reutlingen, employs around 45 people and is managed by Reinhard Rubow (CEO and speaker of the Management Board), Jürgen Klein (Member of the Board, Sales & Marketing) and Dr. Alfred Stett (CTO, Member of the Board).

Innovative mass finishing process increases the efficiency of turbines

Specially selected grinding media improve the airflow characteristics of blades.

Innovative mass finishing process increases the efficiency of turbines

The MV multivibrators are equipped with high-speed imbalance motors.

At the ALUMINIUM 2018 exhibition Walther Trowal presents its new process for the gentle surface finishing of guide vanes used in turbines and compressors. It creates very smooth surface readings and, thus, optimizes the airflow through the guide vanes.

After they have been milled from a cast block of aluminium, guide vanes for turbines or compressors require a very smooth surface to insure optimum airflow around every single blade. To date this required a complex and costly mechanical process.

Walther Trowal has recently developed a method that allows the gentle smoothing of the guide vanes after milling without rounding the leading edges beyond the acceptable tolerances – an important factor for increasing the efficiency of jet engines.

Basis for the new process are the rotary multi vibrators of the model range MV allowing the processing of guide vanes with diameters of up to 800 mm. The company utilizes special, extremely small ceramic grinding media, which provide not only optimum surface coverage on the work pieces but also smoothens the surface at the root of the vanes.

The guide vanes, but also blisks, are mounted to a fixture that is magnetically attached to the base of the processing bowl. This ensures that the overlapping, high-frequency vibrations from the multi vibrator are transferred to the work piece, causing intensive contact between the media and the vane surface areas.

The result of the fully automatic finishing process: The milling lines from the preceding machining step have been ground out creating a very smooth surface. With the new process Walther Trowal reduces the Ra surface readings from 4.0 down to 1.0 µm with only minimal rounding of the leading edges. This innovative mass finishing process creates ideal conditions for an optimum airflow through the guide vanes.

At the ALUMINIUM 2018 Walther Trowal also presents rotary vibrators used for the surface finishing of aluminium castings including the removal of burrs.

Quick digital bentonite testing reduces casting defects

Moulding sands for the foundry industry: Electronic wet tensile strength test provides results in a minute.

Quick digital bentonite testing reduces casting defects

The new WJ1 tester launched by Jung Instruments measures the wet tensile strength of moulding sands.

Jung Instruments“ new WJ1 tester automatically measures the wet tensile strength of moulding sands and displays the measured results as digital readings in N/cm2 within a minute. These measurements increase process security before the casting process starts, reducing overall reworking and rejections.

The wet tensile strength of moulding sands largely depends on their content of active bentonite. Too little bentonite may lead to cracks or spalling in the sand mould, resulting in casting defects, such as scabbing.

With the new WJ1 tester, foundrymen can measure the wet tensile strength in next to no time and adjust the bentonite content as required.

The innovative system is the world“s first to operate fully electronically, using a calibrated load cell, a digital display for the measured results and, as an option, an interface for data transfer.

Carsten Jung, Development Manager at Jung Instruments, sees clear advantages for his customers: „As the measurements take place fully automatically, they are in no way influenced by subjective factors, as for example the skills of the operator. And the instrument is very easy to use: All the operator has to do is push a button for the measurement to start and take the readings. The instrument does not have to be attended as it performs the measurement. This saves time and money, as the operator can perform other tasks while the measurement is going on.“

The technology in detail

The tester measures the tensile force at which a standard test specimen breaks in a tensile test. The specimens are produced by filling sand into a testing tube and pressing in a liftable ring at the top end of the tube. The tube with the specimen is placed into the instrument and heated at approximately 300 °C. The heating is continued until the fracture surface that will result from the imminent breakage will have reached the top rim of the specimen tube. According to practical experience, this will take approximately 35 seconds. By this heating procedure, a condensation zone is generated in the specimen which in sand casting is a critical parameter for the avoidance of scabbing.

Upon reaching the end of the heating time, the ring is automatically pulled upwards causing the specimen to break. The tensile force measured during the breaking process is equal to the wet tensile strength. It is indicated on the digital display in N/m2.

The entire procedure takes place fully automatically. The operator starts the measurement by the push of a button and can take the readings within a minute.

About Jung Instruments:

Jung Instruments GmbH, founded in 2008, develops and manufactures measuring instruments for the foundry industry. Within its product range, the company specializes in standard-conforming moulding sand testers, which it designed in cooperation with the German Foundry Association (BDG) and the Austrian Foundry Research Institute (OGI).

Science Research Technology

Gentle finishing of extremely hard surfaces

Overlapping rotational work piece movement is the basis for even, all-around surface finishes

Gentle finishing of extremely hard surfaces

The spindles allow the processing of batches of up to 18 work pieces. For this photo different work

At this year“s IMTS Walther Trowal is introducing the new drag finisher M-TMD 6M for treating high-value components that require a first-class surface quality. The new drag machines will place a mirror polish on the hardest materials – even on ceramic components. With these machines the costs for polishing can be reduced to a fraction of the costs for manual surface grinding and polishing. But even more important: They ensure absolutely repeatable, high-quality finishing results within an extremely narrow tolerance band.

Walther Trowal developed these new machines specifically for treating high-value components requiring extremely careful handling for the complete finishing process. For example, they are utilized for finishing the surface of turbine blades, impellers for turbo chargers, precision components for pumps and compressors as well as for orthopedic implants.

The new drag machines of the M-series have a carousel with multiple rotating workstations. In turn each workstation is equipped with spindle heads containing several spindle drives onto which the work pieces are attached with special fixtures. In addition, these machines also contain a stationary work bowl filled with grinding or polishing media. As the work pieces are „dragged“ through the stationary media mass, the simultaneous rotational work piece movement by carousel, workstations and spindles creates different overlapping patterns, which ensure an even and intensive coverage of the complete work piece surface.

Christoph Cruse, director of sales at Walther Trowal, foresees a big demand for these machines at some of his customers who produce delicate, high-value components. He explains: „With our new machines we want to assist the manufacturers of work pieces that must receive the best possible surface finish, and where even the slightest surface flaw or scratch might cause them to be scrapped. Furthermore, we target parts where deviations from the dimensional specifications of a few thousands mm can be a detrimental. The M-TMD drag finishers with their perfect surface coverage open brand-new possibilities for finishing such work pieces.“

Die M-TMD 4 drag finisher is equipped with four work stations and can process 12 parts in one single batch; the M-TMD 6 – with six work stations allows batch sizes of up to 18 pieces.

At this year“s IMTS Walther Trowal also displays a range of mass finishing equipment including rotary vibrators, the MV multi vib vibrators and a high-energy centrifugal disk finishing machine.

One drag finishing success story:
Polishing of the extremely wear resistant ceramic coating on orthopedic implants

One example for the successful use of the new drag finishers is a process, specifically developed by Walther Trowal, for polishing of knee femorals made from a chromium-nickel alloy, which are covered with a ceramic coating applied with a special vapor deposit method. To date these parts had to be finished manually in time consuming multiple steps with the risk of high quality fluctuations.

After a pre-grinding step the ceramic coating is polished in the new M-TMD drag finisher with a polishing medium specifically developed for this application. The result: Although the ceramic coating is extremely hard, the drag finisher produces a very smooth, shiny and highly wear resistant finish from the initially rough surface condition. The new coating extends the fatigue life of the implants from to date about 20 up to 30 years!

In developing this process Walther Trowal took an entirely new approach. Instead of using relatively soft polishing materials the company is adding an extremely hard substance to the polishing medium, namely diamond powder.

Christoph Cruse explains the advantages of the new process as follows: „Soft materials can be polished relatively easily. But the manual polishing of extremely hard coatings has been extremely difficult, especially because an even surface finish is essential for the functionality of the component. In the case of vapor deposit coating, with a layer thickness of just a few microns, it is essential not to remove too much of the coating material from the part surface. With the M-TMD drag finishing technology and the new polishing media we have resolved this difficulty: The finish is absolutely even on the entire surface area of the implants.“

The technical details

In standard drag finishers the work pieces are directly mounted to the workstations and „dragged“ through the stationary media bed producing an extremely high processing intensity. This method is more than adequate for most work pieces and produces excellent finishing results.

The new M-TMD systems allow one additional rotational movement, namely that of the spindles mounted to the workstations. The multi-spindle heads on the workstations can be also be angled allowing the adaptation of the media coverage on the work piece surface to different work piece geometries.

All process steps, from cut-down, over surface smoothing to the final polishing, take place in the same machine, without having to remove the work pieces from the spindles.

The new drag finishers are suitable for dry as well as wet processing. In wet processes for cut-down, surface smoothing and, occasionally, for polishing, special finishing compounds are used. For the targeted edge radiusing within a tolerance range of a few thousands mm, like for example for tungsten carbide drill bits or milling tools, dry grinding media are utilized. Dry processing is also used for high gloss polishing with special pastes and polishing media.

(Stuttgart/Reutlingen) – During the Science2Start award ceremony held at the BioRegio STERN 2018 summer party, four teams of scientists and entrepreneurs were honoured for their ideas, all of which boast enormous economic potential. First place was awarded to Professor Bernhard Hirt from the University Hospital Tübingen’s Institute of Clinical Anatomy and Cell Analysis for his idea of the formaldehyde substitute „aminolipin“. Second place went to a software solution for genetically analysing bacterial strains to effectively combat multiresistant bacteria. Tying in third place were two lab-on-a-chip test systems for developing medication to treat neurodegenerative and retinal diseases. The Reutlingen-based artist Jenny Winter-Stojanovic wowed a long list of guests from the worlds of science, business and politics with a spectacular live installation created with cling film in the Tübingen observatory.

Last Thursday, the 2018 winners of the tenth „Science2Start“ ideas competition were announced at this year’s joint summer reception held at the Tübingen observatory. The event was organised by BioRegio STERN Management GmbH, the Verein zur Förderung der Biotechnologie und Medizintechnik e. V. (Society for the Promotion of Biotechnology and Medical Technology) and Tübingen-Reutlingen Technology Park (TTR). In his keynote speech on leadership, Dr. Peter Heinrich – serial entrepreneur, founder of Medigene AG, and co-founder and spokesman for the Executive Board of BIO Deutschland – quoted the poet and author Antoine de Saint-Exupery: „If you want to build a ship, don’t drum up the men to gather wood, divide the work and give orders. Instead, teach them to yearn for the vast and endless sea.“ Giving some advice to the future entrepreneurs, Dr. Heinrich then said: „The trick to leadership lies, among other things, in creating an atmosphere and the necessary conditions to motivate people to work together towards goals.“

Although the four winners of the tenth ideas competition are just starting out in the world of business, the specialist panel of Science2Start judges viewed their projects as boasting great economic potential. Leading the way was Professor Bernhard Hirt from the University Hospital Tübingen’s Institute of Clinical Anatomy and Cell Analysis with his idea of the formaldehyde substitute „aminolipin“. Second place was awarded to Dr. Wei Ding and Benjamin Buchfink from the Max Planck Institute for Developmental Biology in Tübingen for their „PanX+“ software, which is designed to genetically analyse bacterial strains and thus effectively combat multiresistant bacteria. The Natural and Medical Sciences Institute (NMI) at Tübingen University and the Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB) from Stuttgart tied in third place with their lab-on-a-chip test systems for developing medication. The „3D in vitro platform“ developed by Dr. Paolo Cesare targets neurodegenerative diseases, while the „retina-on-a-chip“ presented by Dr. Christopher Probst focuses on treating retinal diseases. The prize money awarded totalled 4,500 euros and, as in previous years, was donated by Voelker & Partner, a firm of lawyers, tax consultants and auditors.

At the subsequent summer reception organised by BioRegio STERN Management GmbH, numerous researchers, entrepreneurs and politicians discussed various exciting topics until late into the evening. One topic of conversation was Jenny Winter-Stojanovic – the Reutlingen-based artist gave guests a live performance, producing a sculpture with cling film that, in combination with the lighting, created a sensational membrane structure stretching from around the iron pavilion into the Tübingen observatory. Hosting the event, BioRegio STERN’s Managing Director Dr. Klaus Eichenberg was delighted to see the art installation give guests food for thought. „Entrepreneurs need to have inspiring ideas and implement them creatively if they want scientific ideas to result in success. They need good connections, too. We are able to help in this respect – by hosting this event, for example,“ said Dr. Eichenberg.

Descriptions of winning projects from the 2018 Science2Start ideas competition

1st place: „Aminolipin“ developed by Prof. Bernhard Hirt from the Institute of Clinical Anatomy and Cell Analysis at Tübingen University
The team of the Institute of Clinical Anatomy and Cell Analysis has developed the substance Aminolipin as a fixing and preservation agent for solid specimens, organs and tissue. It inhibits enzymes that are responsible for decomposition, exhibits a wide antimicrobial efficacy spectrum and is highly efficient in halting the process of putrefaction. Until now, medical professionals have used the toxic and carcinogenic substance formaldehyde to preserve biological tissue, and even entire human bodies. Corpses prepared with Aminolipin closely resemble live patients in form, colour and look and therefore help to enhance doctors‘ training.

2nd place: „PanX+“ developed by Dr. Wei Ding and Benjamin Buchfink, Max Planck Institute for Developmental Biology, Tübingen
PanX+ is an interactive software solution for analysing and visualising bacteria genomes to fight off multiresistant bacteria. Dr. Ding developed panX software to quickly evaluate and interactively visualize the pangenome – in other words, the entire gene set of bacteria strains. His team, known as PathoVis, has developed the new PanX+ software, which makes it possible to analyse enormous volumes of data in less than a day. The epidemiological data is visualised, which allows researchers to investigate the causes of bacteria and give hospitals and public health authorities recommendations on how to prevent multiresistant bacteria from spreading further.

3rd place: „3D in vitro platform“ developed by Dr. Paolo Cesare, Natural and Medical Sciences Institute (NMI) at Tübingen University
Dr. Paolo Cesare’s team has produced an innovative brain-on-a-chip platform and managed to substantially develop Cesare’s MEAFLUIT system of microelectrode arrays fitted with microfluid technology, which secured them a Science2Start award back in 2015. The test system can be used to cultivate and interconnect human neurons. In this way, the 3D in vitro platform makes it easier to develop effective medication for Alzheimer’s and Parkinson’s disease, for example, and circumvents the need for animal testing.

3rd place: „Retina-on-a-chip“ developed by Dr. Christopher Probst, Fraunhofer IGB, Stuttgart
„Retina-on-a-chip“ is an innovative 3D in vitro test system. Researchers from the Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB) and Eberhard Karls University of Tübingen have succeeded in simulating the human retina in vitro to enable scientists to undertake more efficient pharmacological drug research for treating as yet incurable retinal diseases such as age-related macular degeneration and retinitis pigmentosa. Compared to current testing methods, the 3D retina model and the vasculature-like perfusion of nutrients gives researchers a much better insight into their object of study. The use of pluripotent stem cells as the raw material also helps to reduce the number of tests carried out on animals in pre-clinical drug research and testing.

Optic chip with a long service life

Success for Retina Implant – retinal implant still functioning after more than 50 months

Optic chip with a long service life

(Reutlingen) – The subretinal implant from Retina Implant AG has successfully demonstrated its long service life under real-life conditions. Implanted back in 2014, the chip is still functional and has enabled a previously completely blind RP patient, now in her 70s, to perceive light. The fact that the implant has thus exceeded a service life of over 50 months is a great technological success for the Reutlingen-based medtech company.

Retinitis pigmentosa (RP) is a degenerative retinal disease that leads to the destruction of the retina and often total blindness in the final stage. It is regarded as a „rare disease“, yet affects 20,000 to 30,000 people in Germany alone and around three million individuals worldwide. Retina Implant AG from Reutlingen has developed a subretinal implant that is able to restore partial sight to people who perceive very little or no light due to various forms of degenerative retinal diseases such as RP.

In Tübingen, an RP patient who had already lost all her sight received the implant in 2014. The chip implanted in the patient, now in her 70s, has been in operation for more than four years – and still functions as it did in the beginning. For instance, the patient can identify light sources and therefore find her way around more easily. „One of the greatest challenges when developing the implant was ensuring the camera chip in the eye would remain functional over many years,“ explains Dr. Alfred Stett, CTO of Retina Implant AG. „Unlike pacemakers and neurostimulators, which have their electronics and battery packaged in a fixed, hermetically sealed casing, our electronic chip is in direct contact with the retina – a light-permeable barrier layer that is a few micrometres thick is the only form of protection.“

The subretinal implant features 1,600 photodiodes and stimulation contacts that partially replace photoreceptors destroyed by RP. The chip is only around 12 square millimetres in size and is placed directly below the fovea centralis, which means it can move with the eye to locate objects. The latest generation of the implant, known as the RETINA IMPLANT Alpha AMS, was awarded CE certification back in 2016. In Germany, the cost of the implant is reimbursed by the statutory health insurance providers.

„Our forecasts regarding shelf life were previously based on ageing tests conducted in the laboratory and on model-based estimates of service life that are commonplace in the aviation industry, for example. These tests and estimates predicted a service life of 4.7 years. Our patient’s experience shows that we are on the right path. This success is the result of 15 years of intensive research and development to give blind people fresh hope,“ says Dr. Stett.
