Real-time detection device for friction nanogenerator contact area based on force feedback principle

Abstract

The invention relates to the field of optical electromechanical equipment, in particular to a device based on the principle of force feedback that can detect the contact area of ​​a frictional nanogenerator in real time. The contact separation between the measured polymer film and the ITO film is controlled by a single-chip microcomputer, and the pressure sensor is used to obtain the changing load signal of the measured polymer film and transmit it to the single-chip microcomputer to provide a position feedback signal for the system; according to the principles of triboelectricity and electrostatic induction, The voltage signal generated by the triboelectric nanogenerator is transmitted to the computer; the image of the contact area between the measured polymer film and the ITO film is obtained by using the optical measurement principle through the CCD image sensor, and the real contact area of ​​the two is calculated by the calculation software. The device can detect the real contact area of ​​the triboelectric nanogenerator in real time, realizes the real-time detection of the relationship between the voltage output performance of the polymer film and its contact area, and provides great convenience for the research field of the triboelectric nanogenerator performance.

[0002] Energy issues are one of the major issues that affect human progress and sustainable development. Various researches on the development of new energy and the reuse of renewable energy are being carried out in full swing around the world; Since the harvesting of mechanical energy, mechanical energy harvesting technologies based on piezoelectric and triboelectric effects have attracted widespread attention from the scientific community, especially the triboelectric nanogenerator proposed in 2012, which has stimulated the research enthusiasm of many teams around the world. The group studied the materials and their relative properties of the triboelectric nanogenerator, and found that the contact area of ​​the polymer film that constitutes the triboelectric nanogenerator largely determines the output performance of the triboelectric nanogenerator; however, the current quantitative research The relationship between the contact area and the output performance mainly depends on software simulation. There are few reports on experimental research, and there is no relevant test and characterization equipment. It is impossible to detect the relationship between the voltage output performance of the polymer film and its contact area in real time.
