Problems solved by technology

[0005] 1) The elastic deformation recovery of the elastic structure is relatively slow, so the electrical signal output response during the electrode separation process will be slower; 2) The elastic deformation has the risk of structural wear and fatigue failure, for example, if the external force is too large or the number of deformations is too large, the elastic The structure will fail, resulting in low stability of the elastic structure

Abstract

The invention relates to the technical field of nano-generators, and provides a magnet-supported vertical contact separation mode nano-generator, which can improve the equipment stability and accelerate the separation movement speed of the generator by using the repulsive force between magnets as the separation restoring force. The repulsive force and the distance between the magnets are in a non-linear relationship, and when the two magnets are close enough, the repulsive force, namely the separation restoring force, is greatly increased, so that the separation movement speed of the generator is further accelerated; in addition, introduction of an elastic structure is avoided, magnet attraction force is used as correction restoring force in separation motion of the generator, it is guaranteed that the movable pole plate group returns to a set position after being separated every time, and then the stability of the generator is improved.

Description

technical field [0001] The invention relates to the technical field of nanogenerators, in particular to a nanogenerator in a vertical contact separation mode supported by magnets. Background technique [0002] With the further development and realization of 5G technology and Internet of Things technology, a huge number of distributed sensor networks are required to meet people's needs for intelligence, informatization, and modernization. However, how to supply power to the widely distributed and large number of sensor networks has become an urgent problem to be solved. The traditional battery power supply is not friendly to the environment, and it carries limited energy and needs to be replaced regularly, which has the disadvantages of increasing time cost and economic cost. [0003] An alternative to batteries is to harvest energy from the environment to power sensors. Among them, triboelectric nanogenerators and electret generators have attracted a worldwide research boom...
