Diamagnetic levitation bistable vibration energy catcher

Abstract

The invention provides a diamagnetic levitation bistable vibration energy catcher in the technical field of microelectronics. The diamagnetic levitation bistable vibration energy catcher comprises permanent magnet components arranged in a substrate in the shape of a Chinese character 'eye', a magnetic levitation oscillator and diamagnetic generation components. The internal baffle plates in the substrate are vertically provided with three empty slots. A middle empty slot is internally provided with a vertical moving magnetic levitation oscillator, the diamagnetic generation components are symmetrically arranged in the middle empty slot with the magnetic levitation oscillator as a center, and the permanent magnet components are symmetrically arranged in the empty slots at two sides. According to the diamagnetic levitation bistable vibration energy catcher, the vibration energy can be captured in a wide frequency range, the mechanical friction is not existed, and the problem that an existing electromagnetic energy catcher has the disadvantages of a narrow application frequency domain and low energy capture efficiency is overcome.

Description

technical field [0001] The invention relates to a technology in the field of microelectronics, in particular to an anti-magnetic levitation bistable vibration energy harvester. Background technique [0002] With the continuous development of microelectronic technology, microelectronic devices are widely used in mechanical engineering, medical engineering, communication engineering and other fields. However, when these devices are operated in harsher environments or implanted in the object to be inspected, the application of microelectronic devices is hindered due to the limited energy stored in the power supply device. Capturing the energy in the natural environment to power electronic devices not only saves energy, but also makes the electronic devices work more stably and reliably. Mechanical vibrations are the most commonly captured energy. At present, vibration energy capture is mainly divided into three methods: (1) the electrostatic method that uses an electrostatic ...
