1P1-F07 電気刺激による骨格筋収縮を用いた体内発電システムの基礎研究 1P1-F07 Basic study on in vivo power generation system using contraction of skeletal muscle generated by electrical stimulation

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.
