technical field [0001] The invention relates to the technical field of energy harvesting, in particular to a wearable all-weather energy harvesting system based on a low-frequency vibration energy harvester array and photovoltaic cells. Background technique [0002] With the increasingly tense energy issues, the use of renewable energy can effectively reduce the demand for fossil energy and reduce carbon emissions. In the daily activities of the human body, a large amount of mechanical energy is generated by body movement, and solar energy exists in the environment at the same time. By collecting these two energy sources at the same time, considerable electrical energy can be obtained whether it is indoors or outdoors.

Problems solved by technology

However, the energy management circuits of existing micro-energy devices such as photovoltaic cells and vibration energy harvesters are designed for 1-2 micro-energy input channels, and it is difficult to efficiently manage the input energy of more than two micro-energy devices at the same time

However, for application scenarios such as human body wear, the parts with a large amount of mechanical vibration energy generally exist in the limbs, head and neck, etc., and the energy distribution is scattered, making it difficult to collect and manage

[0003] In addition, most of the existing technologies are designed for mature energy harvesting architecture systems such as "photovoltaic cells-lithium batteries". The types of micro-energy devices used are single and cannot achieve all-weather energy harvesting. High-efficiency power generation can only be achieved under good lighting conditions, but there is almost no power output under weak lighting conditions such as indoors and at night

[0004] Therefore, there is an urgent need for an energy system that simultaneously inputs and efficiently manages multiple micro-energy sources, which can be applied to various wearable and distributed power generation environments, and can make up for the problem of insufficient output capacity of photovoltaic cells in low-light environments.
