Problems solved by technology

However, the disadvantage of this method is that the electromagnetic induction unit coil and the magnet unit need to be glued or pasted on the clothes, which will lead to poor flexibility and heavy weight of the clothes, which cannot well meet the requirements of flexible wearable clothing.
[0005] That is, in the existing electromagnetic materials, the conductive coils and magnets are basically hard materials, and the weight is relatively heavy, so it is difficult to make them into fibers or fabrics.

Abstract

The invention provides a garment for joint bending electromagnetic induction power generation, a preparation method and application thereof. The present invention evenly disperses the magnetic powder in the yarn, and utilizes the textile technology to obtain the flexible magnetic yarn fabric; When the opposite sides of the knees of the trouser legs are bent and / or knees are bent, the flexible conductive yarn fabric will cut the magnetic induction line in the magnetic field generated by the flexible magnetic yarn fabric to generate electric energy and realize the oblique bending deformation. Generate electricity and store energy to the cutting magnetic induction line, so as to solve the defect that current wearable devices need to rely on external power supply or work with energy storage devices to work normally, and help them to become lightweight, convenient and intelligent and other directions for further development. The preparation method provided by the invention is simple to operate, and the composition, structure and performance of the material can be regulated according to practical applications.

Description

technical field [0001] The invention relates to the technical field of functional textile processing, in particular to a garment with joint bending electromagnetic induction power generation and a preparation method and application thereof. Background technique [0002] The phenomenon of electromagnetic induction refers to the phenomenon in which the magnetic flux passing through the closed loop changes to generate an induced electromotive force. Humans have opened up a way to obtain huge and cheap electrical energy, which is of great practical significance. After this phenomenon was first discovered by Faraday, self-generating devices based on the principle of electromagnetic induction began to appear one after another, and gradually became an important energy harvesting device. The current mainstream wireless charging equipment is made using the principle of electromagnetic induction, and has begun to be widely used. The electromagnetic self-generating device mainly uses...
