Description

Human motion power generation device for gymnasium and manufacturing method thereof

Technical Field

The invention relates to the technical field of electrical devices, in particular to a human motion power generation device for a gymnasium and a manufacturing method thereof.

Background

Two students of the national institute of technology and technology of Massachusetts have designed a floor system, which can collect mechanical energy generated by the movement of walking, dancing and jumping of people in the places with concentrated flows of people, such as railway stations, dance halls, markets, and the like, and convert the mechanical energy into electric energy. They refer to this form of "power generation" as the "crowd electric field". Such a so-called "crowd zone" is designed by two researchers of the massachusetts institute of technology, james glaramem and sedis juchu, who plan to install such a floor system generating electricity by walking vibration in a public place where the stream of people is crowded, and to generate electricity by using the vibration generated by the dense stream of people. However, no special individual movement power generation device is available on the market at present.

Along with the gradual improvement of the living standard of people in China, the attention degree of people to health is higher and higher, the body-building mechanisms in various places are continuously increased like bamboo shoots in the spring after rain, but a large amount of energy consumed by people in the body-building mechanisms is not recycled and generates economic benefits, a large amount of energy is wasted, and meanwhile, the joints of human bodies are easily damaged by violent body-building movement, so that hidden dangers are left for health.

Therefore, a human body motion power generation device for a gymnasium and a manufacturing method thereof, which have the advantages of high mechanical energy conversion efficiency, convenience in maintenance, good fitness effect, joint protection and easiness in popularization, are urgently needed in the market.
