The transducer is a very important part of the ultrasonic instrumentation system. As discussed on the previous page, the transducer incorporates a piezoelectric element, which converts electrical signals into mechanical vibrations (transmit mode) and mechanical vibrations into electrical signals (receive mode).

Measurement of loads in a prosthesis using piezoelectric transducers ... The piezoelectric transducers used have built-in charge amplifiers which greatly reduce problems with interferences and low signal levels. To transfer loads acting on prosthetic pylon to transducers a supporting mechanical system was developed.

Piezoelectric actuators are usually specified in terms of their free deflection and blocked force. Free deflection (Xf) refers to displacement attained at the maximum recommended voltage level when the actuator is completely ... POLING AND WIRING Poling and wiring determine how the same transducer can be used many ways.
