A Nano Piezoelectric Micro Energy System

Abstract

The invention discloses a nano-piezoelectric micro-energy system, which comprises an upper substrate, an upper electrode, a dielectric layer, a lower electrode, piezoelectric nanomaterials, and a lower substrate from top to bottom; an upper substrate, an upper electrode, a dielectric layer, and a lower electrode form a dielectric capacitor; the piezoelectric nanomaterial is located between the lower substrate and the dielectric capacitor; the force from the outside (generated from the collected dissipative mechanical energy) is transmitted to the piezoelectric nanomaterial to cause the material to deform. effect, thereby generating electricity. The nano-piezoelectric micro-energy system can not only reduce the leakage current, improve the efficiency of the nano-generator, but also store the electric energy generated by the nano-generator, and then output it continuously and stably to the consumer or an external device with a higher energy density when needed. storage device. The nano-piezoelectric micro-energy system of the present invention realizes the integration of efficient power generation, conversion, storage and output through structural design.

Description

technical field [0001] The invention belongs to the technical field of nano power generation, energy storage and power supply, and in particular relates to a nano piezoelectric micro energy system. Background technique [0002] With the gradual popularization of portable and wearable devices, the scale and power consumption of electronic products are gradually reduced, which greatly enriches and facilitates people's work and life. However, the energy supply of these devices still uses the traditional chemical battery as the main energy supply device. Although the chemical battery is simple to prepare and easy to use, its energy supply durability is poor, the size is too large, and it pollutes the environment. Therefore, the development of new self-generating energy systems with high power generation efficiency and long service life is the key to solving the energy problems of such electronic devices. [0003] There are documents in the prior art to report the nano piezoelec...

Problems solved by technology

Compared with the previous two reports, this invention has no essential improvement. The electric energy can only be directly output to the outside, the leakage current is huge, the output power is too small, the efficiency is very low, and it can only output pulsed current, which has no practical value.

In addition, this technology uses a flexible substrate and relies on repeated bending to generate electricity, and the service life of the device is very short
