Piezoelectric ceramic ultrasonic Doppler for dynamic detection ultrlasonic PZT ceramics
Description:
Using the piezoelectric ceramic ultrasonic Doppler effect, the ultrasonic transmitter circuit drives the electroacoustic transducer to emit ultrasonic waves, and the ultrasonic probe is placed close to the abdominal wall to face the fetal heart, and the transducer can receive the reflected ultrasonic waves and convert it into electricity. The signal is the ultrasonic echo signal. According to the Doppler effect, the echo signal of the ultrasound hitting a moving object will inevitably generate a frequency shift δ. After the echo signal is amplified by high frequency, the input demodulation circuit demodulates the frequency shift δ representing the fetal heart sound. This enables dynamic detection of the fetus.
