Problems solved by technology

The moisture-sensing module of the present invention is a knitted fabric containing stainless steel fibers, which can save time and labor to measure the moisture content of the fabric and the moisture content of the air. The material of the knitted fabric is soft, bendable, washable, and close to the skin. , which solves the problems that the material of the sensor in the prior art is hard, cannot be bent, cannot be washed, cannot be close to the skin, and has poor wearing performance. The stainless steel fiber has high strength and low resistivity, and the fabric made of it will change with humidity. Significant resistance change, thus overcoming the low accuracy of fabric sensors

Description

technical field [0001] The invention belongs to the field of smart wearable devices and relates to flexible smart wearable devices. Background technique [0002] Humidity includes air humidity and fabric humidity. Air humidity, that is, the moisture content in the air, is usually detected by embedding, electroplating or silk-screening metal electrodes or metal sheets on textiles. The core component of this method is a humidity sensitive resistor. The characteristic of the resistor is that the substrate is covered with a film made of moisture-sensitive material. When the water vapor in the air is adsorbed on the moisture-sensitive film, the resistivity and resistance value of the humidity-sensitive resistor will change. Using this characteristic Humidity can be measured. Commonly used humidity sensitive resistors are lithium chloride, carbon humidity sensitive resistors, aluminum oxide, and ceramics. However, when this traditional hardware sensor is applied to wearable device...
