Abstract

The invention discloses a dandelion-like multi-directional broadband piezoelectric vibration energy collection device, comprising a multi-spherical support body, a vibration base and at least two cantilever beams, the vibration base is fixed to a surface of the multi-spherical support body, and each cantilever beam is fixed to the surface of the multi-spherical support body along different directions; the cantilever beam comprises an elastic metal conductive slice, an upper-layer piezoelectricity ceramic piece, a lower-layer piezoelectricity ceramic piece and a mass block, a fixing end of the elastic metal conductive slice is fixed to the surface of the multi-spherical support body, and the mass block is fixed to a free end of the elastic metal conductive slice, and the upper-layer piezoelectricity ceramic piece and the lower-layer piezoelectricity ceramic piece are respectively adhered to an upper surface and a lower surface of the elastic metal conductive slice in same direction. The dandelion-like multi-directional broadband piezoelectric vibration energy collection device can collect the vibration energy with relatively high efficiency no matter how vibration direction changes or when the vibration changes in multiple directions with multiple frequencies.

Description

technical field [0001] The invention belongs to the technical field of energy and electronics, in particular to a dandelion-shaped multi-directional, broadband piezoelectric vibration energy collection device. Background technique [0002] Environmental pollution and energy shortage are major problems faced by countries all over the world today. The resulting environmental degradation and energy crisis have gradually begun to affect economic development and people's lives. Under this pressure, scientific and technological workers from all over the world began to explore and develop new energy sources. Vibration is a common phenomenon in people's daily life. Due to its high energy density, its potential energy value has attracted more and more attention and thinking of scientific and technological researchers. As a kind of intelligent material, piezoelectric material has positive piezoelectric effect and inverse piezoelectric effect. Mechanical energy can be converted into...
