Embodiment 1

[0094] On a circular copper sheet with a central hole and a diameter of about 10 cm, 60 fan-shaped friction units arranged radially radially with the central hole as a dot are formed by cutting, and the central angle of each friction unit is about 3°. There is a fan-like gap between two adjacent friction units, and the outer edges of all fan-shaped friction units are kept connected. Take another circular acrylic plastic plate with a central hole and a diameter of about 10 cm as a supporting member, and prepare a first electrode unit with the same shape and size as the friction unit on it, and at the same time, the gap between adjacent first electrode units The second electrode unit is formed in the center, and a certain gap is maintained between the first electrode unit and the second electrode unit. All the second electrode units are connected and led out through wires, and are used as one end for outputting electrical signals to the external circuit, and the inner edge of th...

Abstract

The invention discloses a rotary friction power generator, a voltage stabilization output circuit and a power supply device. The rotary friction power generator comprises two electrode units which are arranged in the same plane in a spaced mode and a first component which is alternately in contact with the two electrode units. Under the action of external mechanical energy, friction static electricity carried by the first component is alternately in contact with the two electrode units along with rotation of the first component, then the induction potential difference between the two electrode units is alternately changed, a drive electron flows through an external circuit, and then alternating-current signals are formed to be output. According to the rotary friction power generator, a nanostructure layer is not needed to be arranged on the friction surface, and milliwatt-level power output density per square centimeter can be achieved.

Description

technical field [0001] The invention relates to a power generation device capable of converting mechanical energy in the environment into electric energy, in particular to a rotary friction generator and a voltage stabilizing output circuit and power supply device based on the generator. 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...
