Power generation knitted piece, intelligent sole and intelligent carpet

Abstract

The invention discloses a power generation knitted piece, an intelligent sole and an intelligent carpet. The power generation knitted piece comprises a plurality of conductive shaft yarns arranged ina first direction, and a plurality of knitted yarns interspersed between the plurality of conductive shaft yarns and extending in the axial direction of the conductive shaft yarns, wherein the plurality of knitted yarns and the plurality of conductive shaft yarns form a planar or three-dimensional structure together, wherein the knitted yarns comprise a conductive beam and a dielectric layer covering the conductive beam; the conductive shaft yarns and the knitted yarns deform under an external force, the conductive shaft yarns make contact with the dielectric layers of the plurality of knittedyarns around the conductive shaft yarns, and during the contact and separation processes, an electrical output is generated between the conductive shaft yarns and the conductive beams of the plurality of knitted yarns. According to the power generation knitted piece, the energy conversion efficiency and the electrical output performance of the power generation knitted piece are improved, and meanwhile, the pressure sensing sensitivity is improved, and the application range of friction nanometer power generation fabric is expanded.

Description

technical field [0001] The invention relates to the technical field of nanometer power generation, in particular to a knit piece capable of generating electricity, a smart shoe sole and a smart carpet. Background technique [0002] With the rapid rise and strong attack of modern information technologies such as the Internet of Things, big data, and artificial intelligence, low-power, lightweight, portable, sustainable and renewable energy supply methods have become the main theme of future economic and social development and people's daily life. Urgent needs. [0003] Converting the mechanical energy of motion, which is discarded by people in daily life, into the electrical energy required by wearable devices is one of the most effective ways to solve the fundamental energy needs of people. Frictional nanogenerator is a technology that directly converts mechanical energy into electrical energy through contact electrification and electrostatic induction coupling mechanism. D...

Problems solved by technology

[0004] At present, there have been related reports on triboelectric nano-electric power generation fabrics, but they all have the problems of low energy conversion efficiency and electrical output performance, and it is difficult to meet the power supply requirements of most wearable electronic devices.

In addition, most triboelectric nanogenerating fabrics have poor compression resilience and low pressure sensitivity, making it impossible to achieve high-sensitivity pressure sensing.
