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.
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.
