DFG CRC/Transregio 39 PT-PIESA




In the Collaborative Research Center/Transregio 39 “High- Volume Production-Compatible Technologies for Light Metal and Fiber Composite-Based Components with Integrated Piezoceramic Sensors and Actuators“ - short PT-PIESA- scientific foundations are being developed for the economic production of active structural parts. The current process chains corresponding the component manufacturing and the piezo-modules manufacturing will thus be merged so that the high volume production of active structural components can be possible. The application potential of this system is immense.


Plane light-weight components with integrated sensors and actuators actively reduce their sound radiation and thus make unnecessary the application of heavier insulation materials in the car body within the car manufacturing. Integrated sensors and actuators can be used for the health-monitoring of safe components or for the active modification of the component strength during crash. For the mechanical engineering  are foreseeable numerous applications for the vibration absorption in order to be able to increase the machining quality and the improvement of  the machine dynamics. Materially integrated high-power actuators are needed in the automation technology for pumps, valves and regulatory elements. In medical technology e.g. intelligent prostheses can be produced by means of integrated sensors and actuators.






The CRC/TR 39 PT-PIESA is funded by the German Research Foundation (DFG) since 1 July 2006 and is currently in the third funding period (01 July 2014-30 June 2018).
