摘　　要：Sensors deployed within the Internet of Things(Io T)require a stable and continuous electrical energy supply[1].The traditional approach to provide an energy supply relies primarily on battery power,which has specific shortcomings;these include integration difficulties,the need for frequent charging or replacement,and environmental pollution associated with battery production and disposal.To solve the challenge of delivering an energy supply to sensors,researchers have designed self-powered sensors or have produced power for sensors by scavenging mechanical energy from the surrounding environment.Electromagnetic generators[2],piezoelectric generators[3]and triboelectric nanogenerators(TENGs)[4,5]are common approaches to scavenge mechanical energy.TENGs have been widely used in the development of self-powered sensors and the supply of electrical energy to sensors due to their high performance,low cost,and wide range of potential materials[6].
