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 at all.

Embodiment 1

[0066] The conductive element adopts a metal copper film layer with a thickness of 100nm, the friction layer adopts a Teflon (polytetrafluoroethylene) film with a thickness of 25 microns, and the conductive layer adopts a metal aluminum film layer with a thickness of 100nm. The macroscopic dimensions of these films are 5cm×7cm. The Teflon film and the metal aluminum film are relatively completely overlapped and placed in contact. After the wire is drawn out through the metal aluminum film layer and the metal copper film layer of the above-mentioned triboelectric nanogenerator, under the relative sliding at an average speed of 0.6 m / s, the friction nano The short-circuit current output diagram generated by the generator is shown in Figure 5 . Connect the output terminal of the friction nanogenerator to the full-bridge rectifier, so that the AC current output generated by the friction nanogenerator is converted into a direct current output, and the obtained current output is s...

Embodiment 2

[0069] In this embodiment, on the basis of embodiment 1, only the polytetrafluoroethylene film is modified, and the others are the same as in embodiment 1, and will not be repeated here. Nanowire arrays were prepared by inductively coupled plasma etching on the surface of the polytetrafluoroethylene film. First, about 10 nanometers of gold was deposited on the surface of the polytetrafluoroethylene film with a sputtering device, and then the polytetrafluoroethylene film was placed in an inductor. In the coupled plasma etching machine, etch the side on which the gold is deposited, and pass O 2 , Ar and CF 4 Gas, the flow rate is controlled at 10sccm, 15sccm and 30sccm respectively, the pressure is controlled at 15mTorr, the working temperature is controlled at 55°C, the plasma is generated with a power of 400 watts, and the plasma is accelerated with a power of 100 watts for about 5 minutes of etching , to obtain a polymer polytetrafluoroethylene nanorod array with a length of...

Abstract

The invention provides a nanometer electric generator utilizing sliding friction. The nanometer electric generator comprises a friction layer, a conducting element and a conducting layer, wherein the conducting element is arranged under the friction layer in a contact way; the upper surface of the friction layer is arranged opposite to the lower surface of the conducting layer; when relative sliding friction occurs between the upper surface of the friction layer and the lower surface of the conducting layer by an exerted external force, and the contact area is changed, an electric signal is output to an external circuit by the conducting element and the conducting layer; when a periodic tangential external force is exerted to the nanometer electric generator utilizing sliding friction, alternating current pulse signal output is realized between the conducting element and the conducting layer.

Description

technical field [0001] The invention relates to an electric generator, in particular to a frictional nanometer electric generator which converts the mechanical energy of applied external force into electric 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 significan...
