Integrated micro-nano energy recovery and storage chip and its preparation method

Abstract

An integrated micro-nano energy recovery and storage chip and its preparation method, the chip is composed of a bottom-up base, a middle layer, a top layer, and a power generation positive module, a power generation negative module and a capacitor module nested in the three-layer structure; Among them, the power generation positive electrode module and the power generation negative electrode module respectively contain porous three-dimensional graphene and corresponding positive and negative particles. When the chip is vibrated, the particles collide and rub against the three-dimensional graphene wall to generate positive and negative charges respectively, which are processed by the power management module. Then supply power to the outside; the function of the capacitor module is to store the electric energy converted from the vibration energy when the power generation is greater than the power supply, and to supplement the power supply when the power generation is insufficient. The chip of the present invention integrates energy recovery and storage elements, which can continuously supply power to the outside and store surplus power. The chip is small in size and suitable for mobile consumer electronics and the Internet of Things; the chip is mass-produced using semiconductor technology, with low cost and suitable for large-scale applications.
