The invention relates to a degradable sensor for detecting a human respiratory signal and a preparation method thereof. The sensor comprises a degradable flexible hard rough substrate, a sensing layerarranged on the flexible substrate, electric conductors arranged at the front end and the tail end of the sensing layer and electrodes. The sensing layer is prepared by printing a mixture of graphitepowder, carboxymethylcellulose (also called sodium carboxymethylcellulose which is one sodium salt of cellulose carboxymethyl ether) and deionized water on the flexible substrate. Accordingly, the raw materials of the sensor are easy to obtain, preparation is easy, the cost is low, the materials are degradable, the sensor is environmentally friendly and free of pollution, use is easy, the detection result is obtained rapidly and accurately, and the sensor has the wide application prospect in the fields of exercise rehabilitation, clinic medicine, safety protection and the like. 本发明涉及种用于检测人体呼吸信号的可降解传感器及其制备方法，该传感器包括可降解柔
