Abstract: Harvesting adequate power for actuation in implanted biomedical devices using an electromagnetic field is a challenging task. Previous attempts to actuate and control deep implants have proven difficult and challenging. In this paper we propose an alternative solution to remote powering and actuation of implanted biomedical devices using a novel hybrid magneto-electric energy harvesting approach. This new approach with the possibility for secure operation is demonstrated in this paper through a (Micro-Electro-Mechanical Systems) MEMS device. We have conducted an analytical and finite element model using ANSYS for the proposed power transfer system to confirm that adequate power can be transferred to operate a MEMS based biomedical device. We have shown that our proposed approach is able to generate 1.3 V under shear stress and provides adequate voltage to successfully operate a micropump. Our numerical results indicate directional actuation of an electrostatically actuated diaphragm of a mechanical micropump up to 1.8 μm resulting in a stroke volume of 10% of the total volume of the chamber.
