Abstract

The invention relates to a micro broadband electromagnetic type vibration energy collector in the technical field of micro electro-mechanical systems. The micro broadband electromagnetic type vibration energy collector comprises a base, a low-frequency vibrating table, a medium-frequency vibrating table, an underframe, a high-frequency vibrating table and a top cover, wherein the medium-frequencyvibrating table comprises a first coil, a medium-frequency cantilever beam, a first pin, a first bonding pad and a second bonding pad, the low-frequency vibrating table comprises an outer frame, a spring connection component and a permanent magnet, and the high-frequency vibrating table comprises a second coil, a high-frequency cantilever beam, a second pin, a third bonding pad and a forth bonding pad. By the micro broadband electromagnetic type vibration energy collector, the voltage output can be increased, the application bandwidth can be enlarged, the application scope can be widened, andthe conversion efficiency can be increased. The micro broadband electromagnetic type vibration energy collector is easy for mass production.

Description

technical field [0001] The invention relates to an energy harvester in the technical field of micro-electromechanical systems, in particular to a broadband miniature electromagnetic vibration energy harvester. Background technique [0002] With the rapid development of technologies such as MEMS (micro-electromechanical systems) and wireless sensors, related micro-energy technologies are becoming more and more important. At present, there are generally two types of micro-energy sources: batteries and micro-energy harvesters. Due to the defects of limited energy storage and short life, batteries have greatly limited their wide application. Therefore, miniature energy harvesters that overcome this fatal defect have attracted more and more attention. [0003] Mechanical vibration is a kind of energy that exists widely in nature, so the vibration energy harvester came into being. The vibration energy harvester continuously provides energy for the system, which solves the proble...
