Abstract:	The aging European population leads to the important role of electrically active medical implants for medical therapies. Combined with energy harvesting technology, the power supply life time of the medical implants can be extended. In this work, we introduce a miniaturized thermoelectric generator (TEG), which transforms the thermal energy into electrical energy, embedded in a realistic human forearm model. For efficient design optimization of TEG, we present a combination of model order reduction (MOR) and thermal submodeling methodology. The representative TEG positioned global thermal human forearm model is first reduced to a compact size through MOR method. Secondly, the temperature results from the reduced model are projected back to the full-scale and used as the boundary conditions for the detailed TEG submodel.
