Vibration switch type friction generator and friction generating method

Abstract

The invention discloses a vibration switch type friction generator and a friction generating method. The friction generator comprises a first friction layer whose upper surface is contacted and provided with a first electrode layer, a second friction layer whose lower surface is contacted and provided with a second electrode layer, and a vibration type switch. The vibration type switch enables the two electrode layers to alternate and form electrical communication with an equipotential source. The vibration of the vibration switch is triggered by the mechanical motion of a generator. During a periodically contacting / separating process of the two friction layers, equipotential electric potential is generated on the two electrode layers, and when the two electrode layers alternately communicate with the equipotential source through the vibration switch, alternate currents are generated. Since the frequency of currents outputted by the generator is decided by the frequency of the vibration switch, the output frequency of the generator can be improved by improving the vibration frequency of the vibration switch.

AI Technical Summary

Problems solved by technology

However, at present, the power supply frequency required by industrial and household appliances is generally 50-60Hz, and the output frequency of the friction generator is controlled by the frequency of external force changes. Under the action of low-frequency external force, high-frequency electrical power cannot be obtained output, which cannot meet the needs of high-frequency power supplies for electronic devices
