Abstract

The invention discloses a method for manufacturing a high-electrical-property nano generator based on a piezoelectric-frictional effect. The small-area high-output-voltage nano generator is manufactured on the basis of the piezoelectric effect and the frictional effect. According to the method, CNT particles and piezoelectric particles in a certain proportion are mixed into liquid PDMS to be manufactured into a composite film, a micro-nano concave-convex structure with rules is manufactured on the surface of the composite film through a micro-processing method, finally electric polarization is carried out on the composite film, and an electrode is arranged in a clamping mode. The method combines the advantages of piezoelectricity and friction, and the manufactured piezoelectric-frictional nano generator with the small area, high sensitivity and high voltage output is low in manufacturing cost and simple in process, has good durability and workability, enables large-scale production and application to be carried out conveniently, and can be easily blended in the design of other products. Self-powered and self-driven equipment is provided for personnel electronic products, environmental monitoring, medical science and the like, and huge commercial and practical potentials are achieved.

Description

technical field [0001] The invention relates to the field of micro-nano science and micro-energy technology, in particular to a method for preparing a nano generator with high electrical performance based on piezoelectric-friction effect. Background technique [0002] Micro-nano generator is a small-volume, high-power micro-energy device that has developed rapidly in recent years. It can collect tiny vibrational mechanical energy in the surrounding environment and convert it into electrical energy to power other nano-devices, such as sensors and detectors. Wait to provide energy. The invention of micro-nano generators not only brings the possibility of miniaturization of energy systems, but more importantly, for the realization of nano or microelectronic devices that are completely wireless, bio-implantable, and unattended for a long period of time or even for a lifetime, micro-nano Generators provide an ideal power system. [0003] At present, the most common micro-nano g...
