What is the definition and composition of ultrasonic sensors?

An ultrasonic sensor is a sensor that converts an ultrasonic signal into another energy signal (usually an electrical signal). Ultrasonic waves are mechanical waves with vibration frequencies above 20 kHz. It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directionality, and can be ray and directional propagation. Ultrasonic penetration of liquids and solids is very large, especially in sunlight-opaque solids. When an ultrasonic wave hits an impurity or an interface, it will produce a significant reflection to form a reflected echo, which can produce a Doppler effect when it hits a moving object. Ultrasonic sensors are widely used in industrial, defense, biomedical and other fields.

A commonly used ultrasonic sensor consists of a piezoelectric wafer that can emit both ultrasonic waves and ultrasonic waves. Small power ultrasound probes are used for detection. It has many different structures, which can be divided into straight probe (longitudinal wave), oblique probe (transverse wave), surface wave probe (surface wave), Lamb wave probe (Lamp wave), dual probe (one probe emission, one probe reception) Wait.
