21. Magnetostrictive transducers were pursued after WW2 as an alternative to piezoelectric ones. 22. For radiated emission measurement, antennas are used as transducers . 23. The acoustic impedance of piezoelectric materials facilitated their use as underwater transducers . 24. A transducer may be swept mechanically by rotating or swinging. 25. Hall effect sensors with linear transducers are commonly integrated with digital electronics. 26. Mineralization of the ultrasonic transducers requires maintenance and potential for component failure. 27. The G-protein ( named for the transducer ." 28. It is a piezoelectric material for microphones and other transducers . 29. Previous DTAR configurations only included an under-saddle transducer . 30. Prestin is primarily an electromechanical transducer but pendrin is an ion transporter.
