Description

Technical field: [0001] The invention relates to a miniature energy conversion device, in particular to a device for converting thermal energy, light energy or chemical energy in the environment into electrical energy by using the combined action of polymers and zinc oxide nanowires. Background technique: [0002] With the development of nanotechnology, more and more nanoelectronic devices have emerged, which are widely used in military, biological and other fields. All nanoelectronic devices need a microscopic power supply to supply energy. Only when the power supply is also miniaturized can real system integration be realized and nanoelectronic devices truly "nano". Especially for devices that work in some extreme environments, such as devices implanted in humans or animals, sensors in harsh environments, and electronic devices that work in space, conventional power supply systems cannot provide power, and if batteries are used, there are lifespan limitation. Therefore, ...

AI Technical Summary

Problems solved by technology

Although foreign scientists have proposed a conceptual "nano generator" that uses ultrasonic waves as an external energy source to drive the vibration of nanowires, due to the problems of the device itself, only 0.4nA current is obtained, and it is difficult to obtain a large current signal.

Moreover, all such nanogenerators currently focus on directly using zinc oxide nanowires to convert mechanical energy in the environment into electrical energy, which limits its application because environmental kinetic energy is not available everywhere.
