Manufacturing method of wires applied to wearable device

Abstract

The invention discloses a manufacturing method of wires applied to a wearable device. The manufacturing method includes the following steps that firstly, electric wire base materials are prepared, wherein silver plating treatment is performed on the surfaces of nylon filaments so that silver plated wires can be obtained, and the length specific resistance of the silver plated wires is measured; secondly, twisting and combining are performed, wherein the number of the silver plated wires which meet the final impedance requirement and need to be combined is calculated according to the length specific resistance obtained in the first step, and the silver plated wires and spandex are twisted and combined so that an inner wire can be obtained; thirdly, pipe band coverage is performed, wherein the inner wire obtained in the second step is woven into an insulating pipe band through a band braiding technology and covered with the pipe band; fourthly, finished products are manufactured, wherein the pipe band in which the inner wire is arranged in a covered mode is subjected to steam preshrinking so that final wire finished products can be obtained. By measuring the length specific resistance of the single silver plated wire, the enough-low length specific resistance is obtained by adjusting the parameter (the number of the silver plated wires); the single silver plated wire is thin and has certain elasticity, and the silver plated wires and the spandex are twisted and combined according to a certain number and the twisting degree so that better elasticity can be produced.

Description

technical field [0001] The invention relates to a manufacturing process of a conductive wire, in particular to a manufacturing method of a wire applied to a wearable device. Background technique [0002] The bioelectrical signals emitted by the human body itself, such as heart beating (ECG signal), muscle contraction (myoelectric signal), etc., are collected, filtered, and amplified by electrodes for subsequent analysis. [0003] The outside world can also apply electricity to the human body through electrodes. High-voltage electrical pulse applications such as cardiac defibrillators, and low-voltage electrical pulse applications such as electronic muscle stimulation (EMS) technology can stimulate muscles to make muscles respond to contraction to achieve the effect of exercising muscles. [0004] Among them, the frequency of the current in EMS technology includes both intermediate frequency and low frequency, and the electrodes are arranged in pairs around the muscle groups....

Problems solved by technology

However, if this kind of wire is applied to wearable devices, it will cause insufficient elasticity, and use polymer material insulation to form an insulating protective layer by ultrasonic spraying or sequentially immersing the inner wire in a variety of different polymer solutions or melts. It will make the wire harder and cause discomfort when it is close to the body
