Embodiment

[0020] like figure 1 As shown, a piezoelectric material-based micro power generation device is provided with a piezoelectric material layer 2 and conductive electrodes 3 attached to both sides of the piezoelectric material layer 2 in the housing 1, and the conductive electrodes 3 are connected to the rectifier circuit 4 through wires. , the two output lines of the rectifier circuit 4 are connected to the load 6 . When the present invention is used, the micro power generation device is placed on roads, sidewalks, etc., when a vehicle or pedestrian exerts gravity on the housing 1, the housing 1 will be deformed, causing the piezoelectric material layer 2 to deform, and the piezoelectric material layer 2 will be deformed. The material will release a pair of positive and negative charges, which are provided to the load 6 through the conductive electrode 3 and the rectifier circuit 4 to achieve the purpose of providing power for the load 6; when the gravity applied to the piezoelec...

Abstract

The invention discloses a minisize power generation device based on a piezoelectric material. A piezoelectric material layer and conductive electrodes attached at the two sides of the piezoelectric material layer are arranged in a casing. The conductive electrodes are connected with a rectifying circuit through wires. Two output wires of the rectifying circuit are connected with a load. During use, the minisize power generation device is arranged at places such as a road or a sidewalk and the like. When a vehicle or a pedestrian applies a gravity to the casing, the casing is deformed so that deformation of the piezoelectric material is caused and thus the piezoelectric material releases pair positive and negative charges which are supplied to the load through the conductive electrodes and the rectifying circuit so that an objective of supplying electrical power to the load is achieved.

Description

technical field [0001] The invention relates to the technical field of a micro power supply, in particular to a micro power generation device based on piezoelectric materials. Background technique [0002] When we need to install monitoring devices or electronic signs along roads, railways, and oil and gas pipelines, power supply is a problem we must consider. The existing method is to bury wires, and install photovoltaic or wind power generation if the distance is too far system, these will bring higher costs. On the other hand, with the development of integrated circuits, their integration is getting higher and higher, and the power consumption is getting lower and lower, which provides opportunities for us to use distributed micro-generation devices for power supply. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a micro power generation device based on the piezoelectric material for the deficiencies in the ...
