B02 - Transformation of mechanical energy as internal energy source for electrically active implants

Summary of the work programme

The two main research questions addressed in B02 are how to use mechanical energy from load-bearing implants for conversion into electrical energy; and how to integrate electronic components into such implants without compromising the mechanical safety. For this purpose, finite element analyses are carried out on representative implants using mathematical optimisation algorithms. Functional models are then manufactured and the mechanical fatigue as well as the function of the energy harvesters is tested. In the long term, the energy harvesters will serve to enable electrostimulation therapies as well as measurement functions in implants without external power supply.
