Ultrasonic Medical and Beauty Prodcut, Brand Name : JUDE

The piezoelectric ceramic ultrasonic sensor is very sensitive to the characteristics of piezoelectric ceramic ultrasonic sensors, extremely weak mechanical vibrations can be converted into electrical signals, is widely used in sonar systems, weather detection, remote sensing of environmental protection, household appliances and so on. The earthquake is a devastating disaster, and the source in the depths of the earth's crust, before it is difficult to predict, the human being into a helpless embarrassment. Piezoelectric ceramic sensor sensitive to external force which can be induced to make it even more than ten meters outside the insect flapping wings disturbance on the air, it is used to make piezoelectric seismograph, can accurately measure the intensity of the earthquake, the earthquake indicate the direction and distance. It can not be saidIs a large round piezoelectric ceramics.
