A broadband miniature electromagnetic vibration energy harvester auxiliary device

Abstract

The invention discloses an auxiliary device for a broadband miniature electromagnetic vibration energy harvester, which comprises a base, an S-pole permanent magnet installation slot is opened at the bottom of the base, and the inner side wall of the S-pole permanent magnet installation slot is slidably and tightly fitted with a S-pole permanent magnet, the top of the base is provided with an energy collection slot, the inner side wall of the energy collection slot is fixedly connected with a wall-mounted wire, and the inner side wall of the energy collection slot is slidably connected with liquid metal, when the device is displaced When the liquid metal slides along the inner wall of the energy collection slot, the liquid metal cuts the magnetic field lines generated by the N-pole permanent magnet and the S-pole permanent magnet, thereby generating electric energy, and the electric energy is drawn out through the signal electrode and current output through the wall-mounted wire. The electrode is connected to the energy storage circuit to store the generated electrical energy. This method can work stably for a long time, solves the problems of environmental limitations of traditional devices, and can better convert external energy into electrical energy, saving resources and protecting surroundings.

Description

technical field [0001] The invention relates to the technical field of energy collection, in particular to an auxiliary device for a broadband miniature electromagnetic vibration energy harvester. Background technique [0002] Energy harvesting refers to converting weak energy into electrical energy and supplying it to back-end sensors; usually the available energy includes weak light energy, weak kinetic energy, thermal energy, etc.; the environment where electronic devices are located mostly has a lot of available energy (such as other The electromagnetic fields, vibrations, temperature changes, etc. generated by the device, convert these energy into electrical energy in some way, usually supplying power to small electrical devices (such as the cochlea implanted in the human body, etc.); the idea comes from converting natural mechanical energy or solar energy into electrical energy (hydropower station, photovoltaic power generation); such as using body heat to power small ...

AI Technical Summary

Problems solved by technology

[0003] Most of the traditional energy harvesting devices have the problems of large size, short life, high battery replacement cost or even non-replacement when supplying energy, and there are also problems such as environmental restrictions. Therefore, the traditional energy supply method is not enough to support micro smart devices. For the development of the system, we propose a broadband miniature electromagnetic vibration energy harvester auxiliary device to solve the above problems
