Highly-integrated modular energy collection system and application

Abstract

The invention discloses a highly-integrated modular energy collection system and application, and belongs to the technical field of energy collection systems. The system comprises an upper protection patch, a liquid drop energy patch, a micro-vibration energy patch, a photovoltaic energy patch, a heat energy collection patch and a circuit substrate film; flexible PCBs are arranged on the peripheries of the four energy patches to serve as skirts, patch-shaped electrodes are arranged on different side edges of the skirts of the four energy patches respectively, and four sets of patch-shaped electrodes are arranged on the upper end face of the circuit substrate film in the circumferential direction; when in use, the required energy patches are stacked layer by layer and then fixed between the upper protective patch and the circuit substrate film, and the patch-shaped electrodes of the adjacent energy patches are arranged in a staggered manner, so that the patch-shaped electrodes of different energy patches are placed in different directions and are respectively butted with the four groups of patch-shaped electrodes on the circuit substrate film; and an external interface electrode is arranged on the upper protection patch and is used for being connected with an external load. According to the invention, different energy can be collected and then applied to different scenes, such as the fields of industry and articles of daily use.

Description

technical field [0001] The invention belongs to the technical field related to energy collection systems, and in particular relates to a highly integrated modular energy collection system and its application. Background technique [0002] Energy harvesting refers to the conversion of weak energy into electrical energy for use by back-end sensors. Usually, the available energy includes weak light energy, weak kinetic energy, thermal energy, etc. Most of the environments where electronic devices are located have a lot of available energy (such as, Electromagnetic fields generated by other devices, vibrations, temperature changes, etc.), convert these energies into electrical energy in a certain way, and usually supply power to small electrical devices (such as cochlea implanted in the human body, etc.), the idea comes from converting mechanical energy or solar energy in nature into Electric energy (hydropower stations, photovoltaic power generation), such as using body heat to...

Problems solved by technology

[0003] The existing energy harvesting system technology has the following problems: when the existing energy harvesting system collects external energy and converts electric energy, the traditional energy harvesting equipment such as photovoltaic panels not only has a large production investment and later maintenance costs, but also after the equipment is installed It can only be used at the installation site, and its transfer is difficult, and a single energy harvesting device can only collect a single energy to convert it into electrical energy, which will limit the scope of use of the energy harvesting system
