The strategy of circuit design for high performance nanogenerator based self-powered heart rate monitor system

Self-powered systems based on nanogenerators are good candidates for internet of things and human health monitoring. The energy consumption is analyzed by information process. Fast operation is important to design high performance self-powered wireless sensor systems. According to entropy theory of distributed energy, this study proposes an energy consumption design method of self-powered sensor based on nanogenerator. Self-powered heart-rate monitoring system is improved for wireless body sensor networks. The strategy can overcome the application limitation of self-powered systems with low-quality source.
