Abstract

The invention provides an ultrasonic sensor, which comprises a substrate and an ultrasonic sensing layer, wherein the substrate is used for supporting the ultrasonic sensing layer. The ultrasonic sensing layer comprises a piezoelectric layer and at least one electrode layer which are arranged in a stacked mode, and the ultrasonic sensing layer is used for sending and receiving ultrasonic signals.According to the ultrasonic sensor, the sending and receiving of ultrasonic signals are achieved by the same ultrasonic sensing layer without respectively arranging a signal sending layer and a signalreceiving layer, so the thickness of the ultrasonic sensor is reduced.

Description

technical field [0001] The invention relates to an ultrasonic sensor and a manufacturing method of the ultrasonic sensor. Background technique [0002] In contemporary society, people's own health awareness has generally improved. In addition to the high attention to work and rest, diet and exercise, regular physical examinations are also essential. Ultrasound examination uses ultra-high-frequency sound waves to pass through the human body, and different tissues reflect different degrees of sound waves. After collecting these reflected waves, the computer's precise calculation shows the structure of the body tissue for doctors to judge whether it is normal or abnormal. [0003] At present, ultrasonic sensors have been widely used in medical imaging equipment due to their advantages of small size, low price, and safety. However, the existing ultrasonic sensors usually include multilayer structures such as a protective layer, a signal receiving layer, a substrate, a signal tr...
