Abstract :
A piezoelectric blood-pressure transducer has been developed for indirect blood-pressure measurements on a wrist for the clinical environment. Use of a piezoelectric ceramic beam with a relatively high impedance amplifier provides a position-insensitive pressure measurement, which is very much desirable for a long-term measurement.
