[Abstract] Triboelectric nanogenerator (TENG)-based self-powered microsystem is beneficial for solving the energy problem of Internet of things (IoT). In this paper, the design of the self-powered micro system is investigated, and three fundamental modulus including the human motion-based TENG, active sensor and energy storage unit to establish the self-powered system are proposed. This methodology can effectively overcome the difficulty of energy supply for mass various sensor units in IoT applications, which provides a promising solution for the long term energy supply problem in the IoT technology, and push the IoT forward to multi-dimensional and various morphological developing trend.
