Friction generator for harvesting biological motion energy and method of use thereof

Abstract

The invention relates to a friction type generator which is based on the triboelectrification principle and the electrostatic induction principle and used for collecting biological kinetic energy and monitoring biological motion. The friction type generator comprises a foot sole or a biont, a conductive electrode attached to a human body or the biont, the normal ground surface and the ground or a conductor. The foot sole is a human foot sole or a foot of the biont. The biont is a human body or an animal body. The conductor electrode attached to any part of the human body or the biont is used as a biont electrode, a wire is led out of the conductor electrode to be connected with the ground or the conductor through a load. Compared with a traditional energy collector, the friction type generator is free of extra functional materials, devices and conductive electrodes, and high in voltage output capacity and high in charging capacity. According to a manufacturing method of the friction type generator, the method is simple, cost is low, manufacturing is easy, and usability is high. The friction type generator can be easily integrated with a traditional electronic device.

Description

technical field [0001] The invention relates to a generator based on friction electrification, in particular to a friction generator for collecting biological motion energy and monitoring biological motion based on the principle of friction electrification and electrostatic induction. Background technique [0002] Harvesting energy from the living environment is widely regarded as an effective way to achieve green energy and sustainable energy development, and is expected to play an important role in the energy supply of wireless transmission systems, implanted medical devices, and even consumer electronics. The organism itself is full of various forms of energy, including mechanical energy, chemical energy, etc. Taking the human body as an example, scientific research shows that the energy consumed by the human body per day is equivalent to 800 2500mAh batteries, which can be used by mobile phones for 3 years. [0003] In recent years, friction generators based on the princ...

Problems solved by technology

The two surfaces are quickly separated by the arched structure [Wang, S., Lin, L. and Wang, Z.L. NanoLetters, vol.12, pp.6339, 2012], and a frictional nanogenerator with high voltage output can be obtained. The output voltage The peak value is as high as hundreds of volts, but although the output of the friction generator is very high, there are still relatively few forms for collecting the kinetic energy of organisms, and the application range is also limited.
