Abstract

The invention discloses an integrated mixed-environment energy collecting device. The integrated mixed-environment energy collecting device comprises a plane square spiral rectification antenna, a film solar cell and a permanent magnet sheet, wherein the plane square spiral rectification antenna comprises a microstrip receiving antenna and a wideband rectification boosting circuit, the film solar cell is directly attached to the upper surface and lower surface of the microstrip receiving antenna, a PCB of the microstrip receiving antenna is hollow, and the permanent magnet sheet is located in the middle of the hollow PCB and is connected with the double-layer PCB through non-metal springs in four directions. Radio-frequency electromagnetic wave energy, solar energy and mechanical vibration energy can be collected at the same time by the integrated mixed-environment energy collecting device. The integrated mixed-environment energy collecting device has the advantages of being low in cost, small in size, portable, wide in application environment range and the like and can supply energy to low-power-consumption electronic devices like wireless sensing networks and RFIDs under a plurality of environments so that the low-power-consumption electronic devices will not be limited batteries.

Description

technical field [0001] The invention belongs to the field of environmental energy collection, and in particular relates to an integrated mixed environmental energy collection device. Background technique [0002] Solar energy, radio frequency electromagnetic wave energy, and mechanical vibration energy are three ubiquitous environmental energy sources. The typical power of a solar cell illuminated by sunlight is on the order of mW. In direct sunlight, the energy received by a typical thin-film solar cell is 50-100mW / cm 2 . On cloudy days or indoors, the received power will drop to the μW level. Thin-film solar cells, such as hydrogenated amorphous silicon, typically have a conversion efficiency of 10-20% for light energy. Thin-film solar cells need to reduce material and manufacturing costs while improving conversion efficiency, which is the main challenge in the research and development of third-generation solar cells. In addition to efforts to research and develop low...
