The invention relates to a sensor suitable for passive wireless measurement of torque. The sensor has temperature and vibration compensation functions. The passive wireless torque sensor of the present invention includes four surface acoustic wave resonators with different center frequencies, a small antenna and an elastic shaft of the sensor. The surface acoustic wave resonator of this sensor uses quartz as the substrate of the resonator. The interdigital transducer and reflection grid are deposited on the substrate, and the piezoelectric effect and inverse piezoelectric effect are used to excite and receive the surface acoustic wave. The four surface acoustic wave resonators of the torque sensor are pasted on the elastic shaft according to the design angle. When torque is applied to the elastic shaft, the four surface acoustic wave resonators can respectively detect the deformation in the pasting direction. The four deformations can be obtained by processing the temperature , Torque information after vibration compensation. The four surface acoustic wave resonators are connected with the antenna, which can realize the wireless transmission of force state information. The invention has the advantages of simple structure, small size, light weight, high precision, passive wireless, and is suitable for passive wireless measurement of torque of important shaft parts such as aerospace, transmission machinery, precision machine tools, and heavy vehicles.
