Ultrasonic Ceramics Doppler Fetal Heart Rate Monitoring
Description:
The Doppler effect is an important physical phenomenon of ultrasound. When continuous wave ultrasound is emitted, the Doppler effect occurs when there is relative motion between the sound source and the measured object. When the moving target moves toward the sound source, the wavelength of the reflected wave is compressed, so the frequency increases; on the contrary, when the target moves away from the sound source, the wavelength of the reflected wave becomes longer, so the frequency decreases in unit time.
Piezoelectric ceramic materials: PZT4/5/8, etc., we can also customize according to the specific needs of customers.
