Application of ultrasonic sensors
Ultrasonic sensing technology is applied in different aspects of production practice, and medical application is one of its most important applications. The following uses medicine as an example to illustrate the application of ultrasonic sensing technology. The application of ultrasound in medicine is mainly to diagnose diseases, and it has become an indispensable diagnostic method in clinical medicine. The advantages of ultrasound diagnosis are: no pain, no damage to the examinee, simple method, clear imaging, high diagnostic accuracy, etc. Therefore, it is easy to promote and is welcomed by medical workers and patients. Ultrasound diagnosis can be based on different medical principles. Let's take a look at one of the representative so-called A-type methods. This method uses the reflection of ultrasonic waves. When ultrasonic waves propagate in human tissue and encounter two media interfaces with different acoustic impedances, reflected echoes are generated at the interface. Every time a reflecting surface is encountered, the echo is displayed on the oscilloscope screen, and the impedance difference between the two interfaces also determines the amplitude of the echo.
In industry, the typical applications of ultrasonic are non-destructive testing of metals and ultrasonic thickness measurement. In the past, many technologies were hindered by the inability to detect the inside of the object's tissues. The emergence of ultrasonic sensing technology has changed this situation. Of course, more ultrasonic sensors are fixedly installed on different devices to "quietly" detect the signals that people need.
In future applications, ultrasound will be combined with information technology and new material technology, and more intelligent and highly sensitive ultrasonic sensors will appear.
