Broadband miniature electromagnetic vibration energy collector auxiliary device

Abstract

The invention discloses a broadband miniature electromagnetic vibration energy collector auxiliary device which comprises a base. An S-pole permanent magnet mounting groove is formed in the bottom of the base, an S-pole permanent magnet is slidably and tightly attached to the inner side wall of the S-pole permanent magnet mounting groove, and an energy collecting groove is formed in the top of the base. The inner side wall of the energy collecting groove is fixedly connected with a wall-attached wire, the inner side wall of the energy collecting groove is slidably connected with liquid metal, and when the device generates displacement, the liquid metal slides along the inner side wall of the energy collecting groove so that the liquid metal cuts magnetic induction lines generated by the N-pole permanent magnet and the S-pole permanent magnet, and then electric energy is generated. Electric energy is led out through the wall-attached wire, passes through a signal electrode and a current output electrode and is connected with the energy storage circuit, generated electric energy is stored, the mode can stably work for a long time, the problems that a traditional device is limited by an environment and the like are solved, external energy can be better converted into electric energy, resources are saved, and the environment is protected.

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 the conversion of weak energy into electrical energy for use by back-end sensors; usually available energy includes weak light energy, weak kinetic energy, thermal energy, etc.; most of the environments where electronic devices are located have a lot of available energy (such as other Electromagnetic fields, vibrations, temperature changes, etc. generated by devices), and convert these energies into electrical energy in a certain way, usually supplying power to small electrical devices (such as cochlea implanted in the human body, etc.); the idea comes from converting mechanical energy or solar energy in nature into electrical energy (hydroelectric power station, photovoltaic power generation); such as using body heat to pow...

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
