Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a generator, a preparation method thereof and a generator set. Background technique [0002] With the development and progress of the Internet of Things technology, the demand for sensors is more urgent, and the power supply problem of the sensor power supply module also poses a severe challenge. Due to limited factors such as battery life, in addition to using batteries, we urgently need to develop a variety of energy harvesting methods to supplement the battery as a power supply for sensors, thus enabling the emergence of composite energy devices, such as triboelectric generators. [0003] Currently, the reported triboelectric generators are usually composed of two materials with different friction properties, based on the contact and separation of the two materials to generate electrical signals. Although the friction power generation technology has developed rapidly...
