電気刺激による筋収縮を駆動源とした体内発電機構の研究

抄録

We proposed an active in vivo power generation system using electrical muscle stimulation as an alternative to an implanted battery and a-transcutaneous drive line. In this system, skeletal muscle contraction generated by applying electrical stimulation was used to drive a power generator. In this paper, an electromagnetic induction type one was designed to be compact, durable and efficient. The muscle contraction is transmitted to an oscillator supported by parallel leaf springs through a non-contact clutch mechanism using magnetic force. The experimental electric power generation was 20.9 μW, and the energy efficiency was 24.7%.
