This copolymer has the highest electromechanical coupling coefficient k[sub t] among all TrFE compositions and has thus attracted considerable interest in ultrasonic transducer applications. The effect of dielectric relaxation on the performance of VDF-TrFE transducers is discussed.Dielectric devicesCongressesDielectric devices537.24Institute of Electrical and Electronics Engineers, Inc.
