approach
A total of 3 research groups from HTW (AG Schultes) and UdS (AG Seelecke, AG Rizzello) are working together on the realization of this project. Computer-aided model-based and FEM simulations (AG Rizzello) are used to understand, visualize and optimize the electro-mechanical processes of the DE actuator arrays. Furthermore, the interaction between adjacent array points can be investigated by simulation. The insights gained from this flow into design optimization and the development of solution approaches for possible prototypes. In addition, algorithms for self-sensing and for controlling the actuators are developed in this work package.
In parallel, the working group Seelecke is working on the practical implementation of the DEA array in the second work package. The goal is to develop a functioning overall system in which all aspects such as production, construction, contacting, control, etc. must be coordinated. The insights gained here are directly incorporated into the simulations from the first work package, which in turn allows better predictions to be made for further iterations.
The third work package explores the development of novel metallic extensible electrodes, which still have good electromechanical properties even after several million cycles. Metallic thin films, which are sputtered onto a prestressed silicone film, are the focus of the work. By means of a laser, almost any electrode geometry is to be cut out. The resulting design freedom plays a decisive role in the minaturization and optimization process.
