Abstract

The invention discloses an electromagnetic triboelectric hybrid energy harvester for low-frequency motion, which includes an electromagnetic module, a triboelectric module and a spring mass module; the electromagnetic module includes a shell, a magnet frame, a magnet array, a coil array, a coil frame and a coil The magnetic column, the spring mass module includes a spring, a mass block and two end caps, and the triboelectric module includes a plurality of nano friction power generation units connected in sequence; when the energy harvester is excited, the magnet assembly generates motion, according to Faraday's law of electromagnetic induction , the electromagnetic module generates a voltage. The movement of the magnet assembly due to external excitation also causes contact and separation between each triboelectric unit and generates a voltage. Since the energy harvester is designed with a low resonant frequency, it can effectively harvest energy from human motion.

Description

technical field [0001] The invention relates to the technical field of energy collection, in particular to an electromagnetic triboelectric hybrid energy harvester for low-frequency motion. Background technique [0002] In recent years, human's demand and consumption of energy have been increasing day by day. However, traditional energy sources such as petroleum, coal and various chemical batteries have many inherent disadvantages, such as environmental pollution and limited service life. In order to make up for these shortcomings, harvesting energy from the surrounding environment has become a frontier research focus, such as solar energy, wind energy, tidal energy, etc. Among them, piezoelectric, electromagnetic or triboelectric energy harvesting methods, which have shown excellent potential for small-scale energy conversion in portable electronic devices, are attracting attention. [0003] For the common sustainable energy around us, such as wind, human motion or tide, e...
