Stretchable self-power system, preparation method and wearable equipment

Abstract

The invention provides a stretchable self-power system based on foldable carbon cloth paper. The system comprises a stretchable frictional nanometer generator, a stretchable super capacitor and a rectifier bridge; the stretchable frictional nanometer generator comprises silicone rubber and a first carbon-fiber-cloth electrode sealed in the silicone rubber; the stretchable super capacitor is sealed within the silicone rubber and arranged separate from first carbon fiber cloth, and can be deformed under an outside tensile force, bending force and / or torsional force and basically recovered to the original shape when the outside tensile force, bending force and / or torsional force disappears; and the rectifier bridge converts an AC electric signal output by the stretchable frictional nanometer generator into a DC electric signal, and outputs the DC electric signal to the stretchable solid super capacitor. The stretchable frictional nanometer generator and the super capacitor are packaged into an integral body, the size of the device can be reduced greatly, the stretchable performance is high, and electric energy generated by the stretchable frictional nanometer generator is high in performance.

Description

technical field [0001] The invention relates to the field of flexible electronic devices, in particular to a stretchable self-power supply system, a preparation method and a wearable device. Background technique [0002] With the progress of society and the improvement of people's living standards, flexible electronic devices and smart wearable products have received more and more attention. Artificial electronic skins, flexible touch displays, smart watches, health and sports monitoring products, etc. have appeared in people's work and life. These flexible electronic devices require matching batteries to work normally, and the current batteries not only do not have self-charging function, but also have short battery life, which greatly limits the practical application effect of flexible electronic devices. [0003] The most widely used application at present is to combine photovoltaic solar cell modules with supercapacitors or lithium-ion batteries, so that energy harvesti...

Problems solved by technology

However, the movement of the most frequent parts of the human body is irregular, so the output converted into the friction nanogenerator is also an unstable peak AC output, which cannot directly supply power to flexible electronic devices. Therefore, it is necessary to combine a An energy storage device capable of converting and storing the electrical energy of a triboelectric nanogenerator, forming an integrated system of power generation and energy storage
