Abstract

The invention relates to a frictional power generator with a piezoelectric enhancement effect based on miura-ori folding, and the generator comprises a miura-ori folding support base layer, and the support base layer is folded into M*N folded blocks, wherein the front and back surfaces of each folded block are provided with plate-shaped power generation modules. The power generation modules are divided into first modules and second modules, wherein the first and second modules are respectively set at intervals on the row and column of the folded block matrix. Each first module comprises a friction layer and a bottom electrode layer, and each second module comprises a top electrode layer and a piezoelectric enhancement layer. The bottom electrode layers of all first modules are connected together to form one power output end through a first conductive film line attached to the surface of the support base layer. The top electrode layers of all second modules are connected together to form one power output end through a second conductive film line attached to the surface of the support base layer. The generator is small in size, and is strong in output capability.

Description

(1) Technical field: [0001] The invention relates to a friction generator, in particular to a friction generator based on miura-ori folding and having a piezoelectric enhancement effect. (two), background technology: [0002] With the rapid development of modern society, electronic devices and systems are constantly evolving towards miniaturization, portability, and multi-function, which will inevitably lead to the integration of many different types of sensors in a single electronic device. How to supply power to these huge number of micro-sensors has become an urgent problem to be solved in the development of electronics industry and information technology. As a new energy harvesting technology, triboelectric generators can convert extremely small mechanical energy into electrical energy, and have great application potential in the fields of electronic products, environmental monitoring, and medical equipment manufacturing. The surface charge density is an important techn...
