Fetal Doppler Application:

Fetal doppler is ultrasound Doppler devices used to detect fetal heartbeat.The Doppler probe sends high frequency sound waves into the body. It shouldn't be mixed with radiation. When the position of the fetal heart reflects the ultrasound waves, the frequency of the waves is changed. The fetal Doppler receives the reflected sound waves and uses the Doppler Effect concept to calculate the change in frequency and provides an audible simulation of the heartbeat. This sound is then amplified through the headphones. Fetal Dopplers have been around for many decades, and no adverse effects have ever been reported from their use.

PZT Material:

- PZT4 Piezoelectric ceramics have a double behavior of receiving and transmitting, with higher sensitivity and lower dielectric loss.

- PZT5 Piezoelectric ceramics have higher electro-mechanical coupling coefficient, the moderate dielectric constant and higher sensitivity.

- PZT8 Piezoelectric ceramics of high power transmission type have good piezoelectric property, high mechanical strength, high coercive field, low dielectric loss in strong fields.
