Abstract

The invention discloses a stretchable energy conversion fiber strip and a preparation method thereof. The stretchable energy conversion fiber strip comprises two stretchable electrode layers, a stretchable polymer layer and a stretchable piezoelectric layer, and the stretchable electrode layers are a stretchable electrode layer A and a stretchable electrode layer B. The fabric formed by the stretchable energy conversion fiber strips through cross weaving can convert mechanical energy of multiple degrees of freedom and large stretching strain movement of human limbs into electric energy, and can be used as a stretchable electric energy supply device to provide electric energy for wearable flexible electronic products.

Description

technical field [0001] The invention relates to the technical field of textile fibers, in particular to a stretchable energy conversion fiber strip and a preparation method thereof. Background technique [0002] With the advent of the era of flexible and intelligent electronics, traditional battery power supply methods have been difficult to meet the long-term and reliable power supply requirements of increasingly diverse and highly flexible wearable electronic terminals. Development of new portable power supply devices with high power density, durability and soft comfort It is very urgent. Considering the cleanliness and reproducibility of the mechanical energy of human motion, combining energy-transforming materials with human clothing to form smart power-generating fabrics, and harvesting energy from human motion is one of the best solutions to realize portable energy-supply devices. However, most of the existing smart power generation fabrics do not have multi-direction...
