This lecture covers the principles of piezoelectric sensors, focusing on the Doppler effect ultrasound flow meter. It explains the conditioning process involving frequency demodulation with double phase detection, oscillator, and amplifier. The lecture also discusses examples of applications in medical instrumentation, such as continuous monitoring in the carotid artery and the pulsed Doppler method for velocity computation.
