Problems solved by technology

These generators all require relatively concentrated and high-intensity energy input, and it is basically impossible to effectively convert the kinetic energy of low intensity generated in people's daily activities and existing in nature into electrical energy.
At the same time, traditional generators are large in size and complex in structure, and cannot be used as power supply components for microelectronic devices

Abstract

This invention provides a friction nanometer generator and a gyroscope applying the same. The friction nanometer generator comprises an inner core and a housing wrapping the inner core. A plurality of a first friction unit are positioned on the outer surface of the inner core; a plurality of second friction units are positioned on the inner surface of the housing; the upper surfaces of the first friction units face the upper surfaces of the second friction units or the inner surface of the housing; at least part of the first friction units are not in contact with the second friction units; under the action of the external force (impact force), the inner core can move in a reciprocating manner relative to the housing to enable the upper surface of at least one first friction unit to be in contact with or separated from with the upper surface of at least one second friction unit; and electric signals are produced between first conductive units and second conductive units. The friction nanometer generator can convert the mechanical energy produced by vibration, impact forces, wind forces and tide to the electric energy and can also be used as the self-driving gyroscope for the two-dimension space or the three-dimension space.

Description

technical field [0001] The invention relates to the field of energy conversion, in particular to a frictional nanogenerator for converting mechanical energy into electrical energy, and a gyroscope using the triboelectrical nanogenerator. Background technique [0002] Today, with the rapid development of microelectronics and material technology, a large number of new microelectronic devices with multiple functions and high integration have been developed continuously, and have shown unprecedented application prospects in various fields of people's daily life. However, the research on the power supply system matched with these microelectronic devices is relatively lagging behind. Generally speaking, the power supply of these microelectronic devices all comes from batteries directly or indirectly. Batteries are not only large in size and heavy in weight, but also contain toxic chemical substances that are potentially harmful to the environment and the human body. Therefore, it...
