Abstract

The invention relates to the technical field of nano-energy generation, and discloses a nangenerator. The nangenerator comprises a rotor, a stator, and an isolation layer disposed between the rotor and the stator. One part of the rotor, a first part of the stator and the isolation layer form a friction generator. Moreover, the other part of the rotor and the second part of the stator form a magnetoelectric generator, and the third part of the stator form a thermoelectric generator. The nanogenerator achieves the stable DC current output through the coupling of a triboelectric effect, a magnetoelectric effect and a thermoelectric effect, can supply renewable electric energy to various types of electronic equipment, and solves problems that an existing external power supply is limited in storage capacity and causes environment pollution.

Description

technical field [0001] The invention relates to the technical field of micro-nano energy power generation, in particular to a nanometer generator. Background technique [0002] With the rapid development of mobile electronic devices, people rely more and more on those devices for communication, security and sensing. All of these devices currently require an external power source, such as a lithium battery, which has a limited energy storage capacity and has environmental pollution problems. Correspondingly, the use of lithium batteries cannot meet the high power demand in remote areas or specific environments. For example, when scientists or explorers in developing countries or regions cannot meet the needs of traditional electric energy during the expedition, it is crucial to develop renewable mobile energy driven by human motion. There is therefore a need for a device that can use human motion to power electronic devices. Contents of the invention [0003] The purpose...
