Problems solved by technology

However, in this triboelectric nanogenerator, two materials with different frictional properties are in contact with and separated from each other through an elastic separation material, and automatic separation and contact cannot be realized. Not only the structure of the generator is complicated, but also the external mechanical energy The scope is also limited by the structure

Abstract

This invention provides a friction nanometer generator, comprising a housing and an core body which is positioned within a cavity of the housing and can move freely. The core body, from the inside to the outside, successively comprises an inner core, a first conducting layer attached on the outer surface of the inner core and a first friction layer which is positioned on the outer surface of the first conducting layer in a contact manner. The outer surface of the first friction layer faces the cavity. The housing, from the outside to the inside, successively comprises a housing, a second conducting layer attached on the inner surface of the housing and a second friction layer which is positioned on the inner surface of the second conducting layer in a contact manner. The inner surface of the second friction layer faces the cavity. Under the action of the external force, the core body moves within the cavity, which enables the outer surface of the first friction layer to be contact with or separated from the inner surface of the second friction layer, and the first conducting layer and the second conducting layer can output electric signals to the external circuit. The friction nanometer generator disclosed by the invention is simple in structure and is wide in application.

Description

technical field [0001] The invention relates to the field of energy conversion, in particular to a friction nanogenerator capable of converting mechanical energy into electrical energy. 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 is of great significance to develop technologies th...
