While conventional sensor concepts are often not suitable for micro dimensions and too expensive, the new sensor system MicroDetec is ideal for continuous operating mode and sensitive flow conditions in microreactors. The measurement method exploits the phenomenon, that the fluids in biphasic flow in non-conductive micro channels undergo a polarization. This polarization is monitored by an electrode, which is flush fitted on a non-conductive channel (e.g. PTFE). To improve the signal / noise ratio, the measuring point is electrically shielded and the measuring signal is amplified. Micro process technology offers a lot of potential for the intensification of chemical, biochemical and pharmaceutical production. MicroDetec is protected by an international patent application. A first operating prototype has been built. PROvendis is offering licenses for the invention to interested companies on behalf of the TU Dortmund. There is also the possibility of collaboration with the inventors.

The invention describes a method to detect falls with the help of air pressure sensors. The sensors are attached to the patient’s body facing different directions in order to detect the dynamic pressure caused by a fall. At the same time those parts of the protection equipment protecting the specific part of the body that is likely to experience an impact based on the dynamic pressure are activated.

Metal oxide layers for semiconductor sensors or solar cells (e.g. tandem solar cells based on Cu2O) are usually produced by sputtering (HF or RF sputtering).
The novel method basically involves the controlled addition of hydrogen gas during the proper sputtering process. Thus, signif-icant improvements concerning the electrical properties of for example charge carrier concentration, charge carrier mobility and sheet resistance are achieved

The invention describes a novel heating boiler for wooden pellets for the implementation in CHP plants. Through the use of a counter-flow the air gets cleaned effectively and automatically from ash that is produced while the gasification of the wooden pellets. High temperature corrosion and fouling of the heat exchanger of a stirling engine can be reduced drastically. Up-to-date emission instructions can be reached at high effiency.

The invention describes a method to use of operating vibrations to determine the static stiffness of e.g. car bodies.

Raman imaging is emerging and will have some obvious advantages over fluorescence microscopy. Based on a sweeping source TICO-Raman provides a fully fiber laser based rapid nanosecond hyperspectral stimulated Raman microscopy, spectroscopy and endoscopy. It’s a unique combination of high speed, broad spectral coverage, high spectral resolution and high spatial resolution.
