Mainly depends on the manufacturing chip itself.

Because the Curie point of piezoelectric materials is generally higher, especially the ultrasonic probes used in the diagnosis.

The working frequency is the resonant frequency of the piezoelectric wafer.

The core of ultrasonic probes is a piece of pressure in its plastic coat or metal jacket.

Ultrasonic probes mainly consist of piezoelectric chips, which can transmit ultrasound and receive ultrasonic waves.

People can hear voices because of the vibration of the object, its frequency in 20HZ-20KHZ

Ultrasonic sensors are developed by the characteristics of ultrasonic wave.

In order to obtain information from the outside world, people must rely on sensory organs.

The static characteristic of the sensor refers to the static input signal
