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.
