Wearable perspiration rate sensor and assembly method thereof

The invention relates to a wearable perspiration rate sensor and an assembly method thereof. The sensor comprises multiple layers of fabric, wherein electrodes are arranged on each layer of fabric, the fabric and the electrodes are arranged at intervals, the fabric serves as a substrate and a humidity-sensitive medium of the electrodes, each layer of fabric and the corresponding electrode form a humidity sensor, the capacitance value or the resistance value output by the humidity sensor according to the change of the humidity is also changed, the capacitance value or the resistance value of the humidity sensor and the response time are compared, and the perspiration rate and the change rate of the perspiration rate are obtained. The assembly method comprises the steps of selecting hollow fibers with hygroscopicity to prepare a fabric, and carrying out lamination treatment and leveling treatment on the fabric; processing an electrode on the leveled fabric surface by adopting an ink-jet printing process; and ca
