Abstract

The invention provides a power generation air bag device and an insole or a shoe sole applying the same, and particularly a single-electrode contact structure friction nanometer generator using liquidmetal as an electrode; in a power generation process, the liquid metal moves to be in contact with an air bag to realize friction power generation, so that the problem that the mechanical energy collection efficiency and the buffering effect of a friction nanometer generator air bag device for collecting human foot movement mechanical energy in the prior art are mutually restricted is overcome; and the power generation air bag device in the insole serves as a power generation device which can serve as a self-driven motion sensor while supplying power to equipment.

Description

technical field [0001] The invention belongs to the technical field of micro-nano energy sources and friction nano-generators, and in particular relates to a friction nano-generating air bag device for converting the mechanical energy of human foot movement into electric energy and a power-generating air bag insole or shoe sole using the generating air bag device. Background technique [0002] In a sense, the human body is like a machine, it generates energy all the time, when you speak, the sound causes the air to vibrate to produce sound energy, when you walk, the legs rise and fall and the arms swing can generate energy. There have been relevant literature reports on the friction nanogenerator device used to collect the mechanical energy of human footsteps, such as CN104426418A, but the existing nanogenerator airbag structure applied to insoles is a double-electrode direct contact separation friction generator, and the high The molecular polymer layer triboelectric layer...
