Description

technical field [0001] The invention relates to the field of ultrasonic sensors, in particular to a composite material for ultrasonic sensors. Background technique [0002] Ultrasonic sensors are sensors developed using the characteristics of ultrasonic waves. Ultrasound is a mechanical wave with a vibration frequency higher than that of sound waves, which is generated by the vibration of the transducer chip under the excitation of voltage. It has high frequency, short wavelength, small diffraction phenomenon, especially good directionality, and can be oriented as rays dissemination characteristics. Ultrasound has a great penetrating ability to liquids and solids, especially in solids that are opaque to sunlight, it can penetrate to a depth of tens of meters. Ultrasonic waves will produce significant reflections when they encounter impurities or interfaces to form echoes, and when they encounter moving objects, they will produce Doppler effects. Therefore, ultrasonic dete...
