Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to an energy storage device based on a friction generator. Background technique [0002] The rapid development of personal electronic devices and sensor networks has brought many conveniences to users. At present, most personal electronic devices and sensor networks are powered by energy storage elements such as batteries. However, in this power supply mode, once the power of the energy storage elements is exhausted, they will not work normally. Therefore, how to provide a portable and sustainable power source has become a crucial issue. [0003] In order to solve the above problems, a technology that uses friction generators to supplement power for energy storage components such as batteries has emerged as the times require. Through the surface modification of polymer materials, the design of micro-nano structure and the careful matching of different materials, the triboelectri...
