Abstract
As a method for power supply, we proposed an active in vivo power generation system using an electrical muscle stimulation technology as an alternative to an implantation of batteries and a wireless power transmission. In this system, contractile force generated by applying electrical stimulation to skeletal muscle was used as an energy source. In this paper, based on the results of muscle contraction characteristics by electrical stimulation, an electromagnetic induction type power generation mechanism was designed and fabricated. The power generation performance of the proposed generator was evaluated using the gastrocnemius muscle of a toad and the net power generated in the experiment was 112μW.
