The proposed continuation within the framework of the DFG priority program is based on the results emanating from the current phase 2016-2017. One of the most important research resultscomprises the conception of a 6 dimensional printing process for the fabrication of complex magnatoactive polymer elements. It is intended to continue this research within the framework of the new Phase (2018-2019) with the goal of automatically printing magnetoactivepolymer (MAP) devices. For this it is necessary to precisely control the dispersion density gradient of the magnetic particles within the polymer matrix. To these ends further development of the 6D printing process will be continued and expanded. Initial investigations by theresearch unit Monkman indicate a large number of frequency dependencies of MAP materials. These spectral investigations are intended to shed further light on possible sensor applications. Forthese purposes it is intended to cover as much of the electromagnetic spectrum as possible (from MHz through to UV). The combination of both these research directions will open the door to new and complexer sensor and actuator elements suitable for application inrobotic systems. The geometrical distribution of particles in the polymer using 6D printing has already led to the invention of the magnetoactive electret – a device capable of a number of functions including combined magnetoadhesion and electroadhesion in oneelement.
