Problems solved by technology

[0005] However, the current nano-sensors need an external power supply to drive their work, which not only consumes energy, but also because the power supply is mainly rechargeable or disposable batteries, these power supplies are relatively large, so that the application range of nano-sensors has been seriously restricted. At the same time, the bad impact on the environment after the battery is discarded has also prompted people to work hard to find a more environmentally friendly power source.

Abstract

The invention provides a self-driving photoelectric sensor and a preparation method thereof. The self-driving photoelectric sensor integrates a photoelectric sensor into the structure of a friction nano generator, and the photoelectric sensor is driven by using output signals of the friction nano generator.

Description

technical field [0001] The invention relates to the technical field of micro sensors, in particular to a self-driven photoelectric sensor and a preparation method thereof. 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. [0003] Nature and human life will continue to produce various kinetic and potential energies. How to transform these tiny energies into the source of driving force we need is a direction that people are constantly exploring. In 2006, Wang Zhonglin's research group at the Georgia Institute of Technology proposed the concept of nanogenerators, opening up a new category of energy conversion and application. On this basis, the research group led by Professor Wang Zhonglin made the ancie...
