Problems solved by technology

However, for the previous series of generators, in order to obtain considerable output, it often requires high-speed (linear velocity or angular velocity) motion, or large-scale motion. Obviously, in daily life, such as door switches, taps Rotation, the pull and push of drawers have neither high-speed movement nor long-distance continuity, and it is difficult to generate effective output through conventional triboelectric generators, which limits the application of triboelectric generators known for collecting energy from the surrounding environment. It is necessary Improve TENG so that it can be better applied to everyday life

Embodiment 2

[0024] Example 2 - Charging a Commercial Capacitor

[0025] While charging the capacitor prepared in Example 1, light up 2 LEDs, and it takes 30 seconds to rush from 0V to 4.2V. Such as image 3 shown.

Embodiment 3

[0026] Example 3 - Use as a self-driving gate monitor

[0027] Harvesting multiple forms of energy is especially important for triboelectric nanogenerators known for harvesting energy from the surrounding daily life environment to drive tiny devices, such as the opening and closing of doors, the rotation of faucets, and the pulling and pushing of drawers. Our laminated friction generator can not only collect the mechanical energy of rotating blades, but also collect the energy of translational and vibrating objects. To prove this ability, we choose frequently opened and closed doors as the energy source because their switches are similar to translational and vibrating objects. The characteristics of vibration, and successfully applied to the fully self-driven door monitor, through which the door's opening and closing action can be known in real time. In the experiment, we stacked two laminated friction generators facing each other, with PVC in the middle as an insulating mater...

Abstract

The invention discloses a laminated type frictional power generator which comprises a plurality of stacked metal domes, wherein the metal domes comprise first metal domes and second metal domes provided with PTFE (polytetrafluoroethylene) films on upper surfaces and lower surfaces, the first metal domes and the second metal domes are stacked alternately, the lengths of the metal domes are gradually reduced from bottom to top, all the metal domes are aligned at one end and are clamped together through a fixing part, lead wires are introduced from clamping ends of all the first metal domes and are connected to form an electrode M, and lead wires are introduced from clamping ends of all the second metal domes and are connected to form an electrode P. With adoption of a unique laminating structure, energy can be effectively transferred and stored, the application range of the power generator is greatly enlarged, a page-turning-like moving object can be taken as an energy source no matter how large the movement amplitude is, besides, the laminating structure has higher development and variation space, and the laminated type frictional power generator has energy potentials such as collection of vibration, sliding, rotation and the like.

Description

technical field [0001] The invention relates to a laminated friction generator, which belongs to the field of triboelectric nanometer generators. Background technique [0002] Since the nanogenerator was first proposed in 2006, it has received widespread attention. It can not only provide power for micro devices, but also meet the energy needs of a sustainable society. More and more researchers are devoted to it. Electric effect, triboelectric effect, and pyroelectric effect have prepared a variety of nanogenerators, among which the triboelectric effect is favored for its simplicity and high efficiency. The triboelectric nanogenerator (TENG) using the triboelectric effect has been successfully It collects all kinds of mechanical energy rich in the living environment, such as air flow, water flow, vibration, sliding, rotation, and even sound energy and biological energy. It can be seen that TENG is an efficient and low-cost device for harvesting energy from the surrounding e...
