A Semi-modular and SiC-based Smart Transformer

The exhibit will be displayed at the CAU booth C07 in hall 2 for the whole fair week. On Tuesday, April 24, at 12:00 noon and 3:00 pm Prof. Marco Liserre will present the smart transformator at the CAU booth.

The Smart Transformer (ST) Demonstrator is a hardware prototype developed at Chair of Power Electronics of CAU Kiel, with the aim to demonstrate the high potential of such system, as well as the high performance of the architecture proposed by the research group. The Architecture is based on the modular concept and using a specific topology providing either high performance and economic advantages. Thus, it is very appealing for industry application. Among the several advantages of the modular concept, the easy maintenance is highlighted.

The ST demonstrator is a three-phase system and it connected a low voltage dc with value of 800V and a medium voltage ac with output voltage level of 2.6 kV line-to-line. Moreover, the system can process up to 100 kW of output power. In contrast with traditional scientific community, which normally has used only down-scaled prototypes to investigate this sort of system, the CAU Kiel has developed a realistic prototype considering all application requirements, overcoming most of the implementation challenges.

Adsorptive heat and cold extraction

The exhibit will be displayed at the CAU booth C07 in hall 2 for the whole fair week. On Wednesday, April 25, Prof. Norbert Stock will present his reasearch focus at the CAU booth.

New porous materials will be presented, which can be used in adsorption heat pumps. They were discovered at the Institute of Inorganic Chemistry. Our cooperation partners at the Fraunhofer Institute for Solar Energy Systems in Freiburg were able to show that they are perfectly suitable for use in cooling processes. Energy sources can include low energy waste heat (e.g. district heating, geothermal, solar collectors, etc.), which otherwise would remain unused. Topics of the presentation include the environmentally-friendly production, the up-scaling of synthesis, and the application of these and similar materials for cooling, in adsorption heat pumps, for air dehumidification or for water extraction. A demonstrator will show how it works at the booth.

Audio-PSS Service Solutions

The exhibit will be displayed at the BMBF booth C22 in Hall 2 for the whole fair week. On Thursday, April 26, Prof. Carsten Schultz will present his project at the CAU stage, booth C07, right next to the BMBF.

What is it?
Digitally connected hearing aids improve the quality of life for people with hearing impairments. The more comfortably they are set up and can be used, the more they are accepted.

What is new?
Audio PSS has developed a system which analyses environmental data in real time, and then automatically and flexibly adapts to suit the current sound environment. When setting up the hearing aid, the audiologist takes the collected data as well as the individual sense of hearing into account.

Who benefits from this?
Shorter adjustment periods and more comfort benefit those who wear hearing aids. The audiologist can offer a modern, digital product and an innovative service.

Better than welding and adhesive bonding: sculpture-bonding via "METALANGELO"

The exhibit will be displayed at the CAU booth C07 in hall 2 for the whole fair week. On Tuesday, April 24, Prof. Rainer Adelung will present the polytitanium project at 2:00 pm and 4:00 pm at the CAU booth.

Metal injection moulding is a pioneering additive manufacturing technology with which titanium parts can be produced very flexibly. Using joining technology, the connections between metals and/or plastics should achieve "perfect" adhesion, and therefore should only be separated by a cohesive fracture. At the same time, the procedure should be carried out quickly and flexibly. "Nanoscale sculpturing” is such a procedure. It can be easily used anywhere - even instead of welding - and allows metals to be joined to any plastics. The mobile prototype “METALANGELO”, which is the same size as a welding device, can rapidly “sculpture” aluminium surfaces at room temperature with nanometre precision, so that they can be perfectly bonded with various plastics (also silicones) or metals (including copper).

The polytitanium project pursues the combination of these two technologies, "nanoscale sculpturing" and metal injection moulding. These innovative processes will be demonstrated using a series of exhibits, showcasing different metal and plastic material combinations.

Interactive fisheries management game "ecoOcean"

The fishery game will be displayed at the CAU booth C07 in hall 2 for the whole fair week. On Friday, April 27, Dr. Jörn Schmidt will talk about the relation between fish and men.
Fish are a so-called common-pool resource. This means that a fish in the sea belongs to us all, and only becomes the property of the individual fisherman once caught. Therefore, at first glance, the economic incentive for the fisherman to leave the fish in the sea seems to be low. The fisherman can start earning money right away with every fish he catches. However, if you consider the environmental and economic consequences, it often makes more sense not to catch every single fish now. Because a fully-grown fish in the sea has a long-term value for all of us: it grows and reproduces and maintains the fish stocks for the future. So both the community as a whole as well as the individual fishermen enjoy lasting benefits.
The Cluster of Excellence "The Future Ocean" in Kiel researches sustainable fishing. Experts from the marine sciences have joined forces with economists, legal scholars and geographers in order to investigate how the world's oceans and marine resources can be exploited sustainably.

Interactive Poster "Ocean Observation"

The exhibit will be displayed at the CAU booth C07 in hall 2 for the whole fair week.  On Thursday, April 26, Dr. Toste Tanhua will hold a lecture on Ocean Observation at the CAU stage.

"Ocean Observation - from Sensor to Knowledge” is the latest topic of the digital poster by the "Future Ocean" Cluster, which can be interactively explored or used for lectures. Only with the help of appropriate observations can the data collection be carried out, which is the most important foundation for developing an understanding of the ocean. Statements about the ocean changes, assessments of risks and potentials - but also ways to deal with them - are ultimately based on precise observation and exact data location. The interactive poster shows the changes in the surface temperature of the oceans on the basis of time series of measured data, and provides an overview of the various monitoring systems in the world's oceans.

Ocean observation is researched at the Cluster of Excellence "The Future Ocean" in Kiel. Experts from the marine sciences have joined forces with economists, legal scholars and geographers in order to investigate how the world's oceans and marine resources can be exploited sustainably.

RollFlex: Flexbile organic optoelectronics

The exhibits will be displayed at the CAU booth C07 in hall 2 for the whole fair week. On Tuesday, April 24, and Wednesday, April 25, Prof. Martina Gerken will present her research findings at the CAU booth.

Limited resources in a globalized world require a radical mind shift in energy production and consumption and thus new technologies. Devices made of organic materials such as solar cells and OLEDs offer entirely new characteristics such as mechanical flexibility, light weight, low costs, and semi-transparency. We explain the fabrication and function of these devices and introduce new fields of application such as, e.g., flexible solar cells, wearable technology devices and biosensors.

Silicon as innovative material for future rechargeable batteries

The exhibit will be displayed at the CAU booth C07 in hall 2 for the whole fair week. On Tuesday, April 24, Sandra Hansen presents the new silicon battery at the CAU booth at 11:30 am and 2:30 Uhr pm.

Greater ranges, shorter charging times and a longer service life: developments such as electric mobility or miniaturisation in electronics require new storage materials. Silicon - for years the material of the semiconductor and MEMS industry - could have decisive advantages. It could store ten times more energy than conventional graphite anodes in lithium-ion batteries. But due to its mechanical instability, it has been difficult to take advantage of these benefits until now. Through clever structuring of their surface, the electrodes made of pure silicon presented here utilise their storage potential to the full. Both energy density as well as capacity are many times greater than in current batteries. In addition, they are much lighter than conventional anode materials. The lecture presents manufacturing and application possibilities of silicon anodes.

sonoware: boost your voice in noisy places

The exhibit will be displayed at the CAU booth C07 in hall 2 for the whole fair week. On thursday, April 26 at 11:30 am Stephan Senkbeil will present sonoware at the CAU booth.


For the first time, sonoware will publicly present a generic, scalable system to support voice communication in noisy environments. For this purpose, the various voices are captured via microphones and subsequently amplified through speakers close to the audience. Innovative signal processing ensures that disturbing feedback and background noise are eliminated, so that only the voices of the people speaking are played back.

In addition, sonoware will present an example of optimal voice recording in acoustically badly-disrupted environments, to make this speech signal available to further applications, such as communication systems, hands-free systems or speech recognition. This utilises numerous innovative technologies for adaptive combination of several microphones (beamforming) as well as adaptive noise compensation.

Statusplus: web interface for returning clinical “big data” to personalised medicine

The exhibit will be displayed at the CAU booth C07 in hall 2 for the whole fair week.

Statusplus - an innovative web interface for returning multidimensional, clinical “big data” to personalised medicine: By now, with the help of state-of-the-art molecular biological analysis methods, data is being generated that is becoming increasingly important for medical issues. In this regard, the most modern sequencing processes in particular play an increasingly important role, to assist, for example, with decoding the genetic material of a patient in the shortest possible time. Mainly due to billing reasons, this data is primarily generated in research studies. However, in the typical formats used to date, these results are difficult for doctors and patients to understand. In addition, patients and study participants only rarely gain access to their own data; and if they do, they can usually not make use of the highly-complex information without expert help.

In the future, such individual analyses will become ever more important, because doctors agree: successful diagnosis and treatment can only be achieved if both are tailored as closely as possible to the patient's needs. In order to also enable non-medical experts, which are usually the patients, to access complex medical data, the "Statusplus” portal has been developed for test subjects. Through this portal, complex medical data (blood, heart, microbiome and genome analyses) for 204 north-German subjects has been visually represented and explained, in a clear and understandable manner. Additional data layers are currently being prepared. The Statusplus study is part of the DZHK OMICs resource project, and the associated German reference genome project.

Switchable molecules usable as a contrast agent in medicine

Schaltbare MoleküleThey could make tiny molecular machines, new materials or innovative applications in medicine possible: switchable molecules, which can be controlled by external stimuli such as light or temperature. Their development and their potential applications are explored in the Collaborative Research Centre (SFB) 677 at Kiel University. 

Researchers explain how they function using glass vessels with colourless solutions, which contain so-called spiropyrans. These photoactive molecules change their structures, and thereby their properties, when irradiated with UV light. As a result, coloured structures originate in the irradiated solution, which sprout like mushrooms due to thermal effects. After a short time, the molecules switch back to their original state, and the colour disappears again. 

One future area of application for switchable molecules could be as a switchable contrast agent in medical diagnostics. Conventional contrast agents tend to accumulate bit-by-bit in the blood and tissue, so that the contrast greatly decreases over time. Switchable contrast agents are activated when they are injected, and deactivate by themselves after a certain period of time, so that significantly longer operating times are possible. A catheter for using the switchable contrast agent can be seen at the booth, and a film with x-ray photographs of it.
