Problems solved by technology

CN107890350A discloses a wearable motion sensor, a sensing circuit and a motion detection method, which are provided with a silicon rubber dielectric film layer, upper and lower flexible electrode layers, and upper and lower insulating protective layers; this invention uses some hard solid substrates, so that Sensing devices can cause discomfort when in contact with human skin, and these substrates are generally not breathable, making them unsuitable for use as fabrics
CN103225204A discloses a wearable flexible sensor and its preparation method, comprising a flexible fabric, a conductive electrode layer and a sensor layer, the surface of the flexible fabric is provided with a metal barrier layer, and a gap filling layer is provided between the metal barrier layer and the conductive electrode layer ; Although the invention uses a traditional fabric as the substrate material, its gap-filling layer and sensor layer are dense, which is not conducive to the breathable and sweat-wicking properties of the final fabric, and affects the comfort when wearing
Although this utility model can play a certain effect of keeping warm, it does not have the ability to monitor human body movement and physiological signals, which limits its practical application range
