Abstract

The invention relates to an electromagnetic-friction composite nano generator based on rolling friction, and belongs to the technical field of energy sources. The electromagnetic-friction composite nano generator comprises a friction nano power generation unit, a coil type electromagnetic induction power generation unit and a mechanical power capture unit. Each friction nanometer power generationunit comprises a roller electrode array and a friction electric material array adhered to the outer surface of the central roller. The coil type electromagnetic induction power generation unit comprises a coil and a permanent magnet in the central roller. The mechanical power capture unit includes a central drum, a shaft, and an external energy harvesting component. According to the electromagnetic-friction composite type nano-generator, the central roller and the roller electrode are driven to rotate through input conversion of external fluid energy or rotation energy, alternating current isgenerated under the contact of the roller electrode and a frictional electricity material and the action of electromagnetic induction to be supplied to a load, and collection of the external fluid energy or the rotation energy is achieved and converted into available electric energy.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to an electromagnetic-friction composite nanometer generator based on rolling friction. Background technique [0002] With the blowout development of MEMS and Internet of Things systems, a large number of portable, distributed and low-power wireless communication electronic devices are applied to smart cities or smart factories every year. One of the common denominators present in these devices is the need to power them. However, traditional power solutions can no longer fully meet the power supply requirements of low-power wireless communication electronic devices, and are becoming an unfavorable factor restricting the development of MEMS and Internet of Things systems. Therefore, a new power solution is needed to meet the increasingly complex power supply requirements. As the most promising alternative to traditional power sources, energy harvesting technology is receiving incr...
