Doppler Fetal Heart Rate Monitoring Ultrasonic Ceramics
Description:
The ceramic sheet used in Doppler fetal heart rate monitoring is piezoelectric ceramic chip (piezoelectric ceramics), also known as ultrasonic transducer sheet, piezoelectric transducer sheet, piezoelectric ceramics are ceramics with piezoelectric effect, called piezoelectric ceramics. It is an indispensable and important part in the field of modern electronic technology. Piezoelectric ceramics are widely used in modern communications, radar, sonar, automatic measurement and control, ultrasonic energy conversion, ignition and detonation, ultrasonic sterilization, ultrasonic power, etc. . It has a unique piezoelectric effect characteristic, that is, when it is subjected to a small external force, it can turn mechanical energy into electrical energy, and when an alternating voltage is applied, it will turn electrical energy into mechanical energy.
Piezoelectric ceramic materials: PZT4/5/8, etc., we can also customize according to the specific needs of customers.
