Problems solved by technology

[0002] With the vigorous development of the robot industry, the demand for industrial control ultrasonic probes is increasing, and the sensitivity requirements for the probes are also getting higher and higher. It is: ① Start with the material of the ultrasonic probe to reduce the sound attenuation of the probe; ② Adjust the frequency of the ultrasonic probe; ③ Match between the ultrasonic probe and the circuit, etc. After using these methods, the sensitivity of the ultrasonic probe can be improved to a certain extent, but its sensitivity It still cannot meet the requirements of its application in the robot industry. Therefore, the problem of how to improve the sensitivity of the ultrasonic probe needs to be solved urgently.

Embodiment 1

[0022] Embodiment 1: Piezoelectric ceramic sheet, with reference to Figure 1 to Figure 3 As shown, it consists of two single-layer ceramic sheets 1 stacked up and down. A downward frontal groove 1.1 is provided at a corner of the front side of the single-layer ceramic sheet 1. The two sides of the corner form a concave positive side groove 1.2, and the positive groove 1.1 and the positive side groove 1.2 have the same concave depth and width, and the positive groove 1.1 and the positive side groove 1.2 divide the corner into a single layer In the first electrode area of ​​the ceramic sheet 1, the upward surface of the first electrode area is the first positive electrode surface 1.11, the downward surface of the first electrode area is the third positive electrode surface 1.13, and the left side of the first electrode area is the first positive electrode surface 1.11. The two positive electrode surfaces 1.12, the first positive electrode surface 1.11, the second positive elect...

Embodiment 2

[0025]Embodiment 2: piezoelectric ceramic sheet, with reference to Figure 1 to Figure 3 As shown, it is composed of four single-layer ceramic sheets 1 stacked up and down. A downward frontal groove 1.1 is provided at a corner of the front side of the single-layer ceramic sheet 1, and the two ends of the frontal groove 1.1 extend to the two sides of the corner and are on the corner. The two sides of the corner form a concave positive side groove 1.2, and the positive groove 1.1 and the positive side groove 1.2 have the same concave depth and width, and the positive groove 1.1 and the positive side groove 1.2 divide the corner into a single layer In the first electrode area of ​​the ceramic sheet 1, the upward surface of the first electrode area is the first positive electrode surface 1.11, the downward surface of the first electrode area is the third positive electrode surface 1.13, and the left side of the first electrode area is the first positive electrode surface 1.11.
