Abstract

The invention relates to the field of electronics and discloses a self-charging cloth and a method for power generation by use of the self-charging cloth. The self-charging cloth comprises a frictional generator portion and a capacitor portion which are braided together, wherein the frictional generator portion is used for converting mechanical energy in a human body motion process into electric energy and outputting electric signals; and the capacitor portion is used for storing the electric signals output by the frictional generator portion. By use of the self-charging cloth and the method, the mechanical energy of human body motion can be converted into the electric energy by use of a flexible wearable cloth material and the electric energy is stored such that continuous power supply to a wearable electronic device is realized.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a self-charging cloth and a method for generating electricity using the self-charging cloth. Background technique [0002] The multifunctionality of wearable devices is the development trend of electronics in the future and has huge market demand. However, the currently used batteries have limited power supply capacity, large size, heavy weight, and cannot be deformed and bent, which has become a bottleneck for the development of wearable devices. [0003] Recently, some linear flexible Li-ion batteries and supercapacitors have been reported. In these reports, conductive fiber electrodes usually use metal wires, spun carbon nanotube fibers or graphene fibers, carbon fibers, or fabric fibers coated with carbon materials. However, these above-mentioned methods cannot simultaneously meet the following requirements of fiber electrodes: (1) light weight; (2) low cost; (3) flexible and eas...
