Chip integrating micro-nano energy recovery and storage and working method thereof

Abstract

The invention discloses a chip integrating micro-nano energy recovery and storage and a working method thereof. The chip is composed of a base, a middle layer, a top layer, a power generation positiveelectrode module, a power generation negative electrode module and a capacitor module, wherein the base, the middle layer and the top layer are arranged from the bottom to top in sequence, and the power generation positive electrode module, the power generation negative electrode module and the capacitor module are embedded in the three-layer structure. The power generation positive electrode module and the power generation negative electrode module generate positive and negative charges when the chip is vibrated, and power is supplied to the outside after being processed by a power management module; and the capacitor module comprises a capacitor positive electrode, a capacitor negative electrode and other components, and is used for storing electric energy converted from vibration energy when the generated power is greater than the power supply power, and supplementing power outwards when the generated power is insufficient. Energy recovery and storage elements are integrated in thechip, so that power can be continuously supplied to the outside and surplus electric quantity can be stored. The capacitor positive electrode and the capacitor negative electrode are made of high-density and high-porosity three-dimensional graphene, so that the chip is high in energy density and small in size, and is suitable for mobile consumer electronic products, the internet of things and thelike.
