Design optimization of piezoelectric composite transducer using finite element method
(Trans Tech Publications LTD, 2002)
The effect of size on the performance of the cymbal transducer was investigated by using experimental and computational methods. Cymbal transducers were fabricated with steel endcap materials and piezoelectric ceramic, ...
Displacement amplification of electroactive materials using the cymbal flextensional transducer
(Elsevier Science Sa, 2001)
High performance electroactive materials were studied as the driver element for the "cymbal" flextensional transducer. The compositions included were commercially available Navy Type I and PKT552 lead zirconate titanate ...
Piezoelectric hollow spheres for microprobe hydrophones
(Taylor & Francis LTD, 1999)
Miniature hollow spheres of lead zirconate titanate have been prepared with a coaxial nozzle process using fine grain slurry of PZT-5. Following the binder burnout and sintering, the spheres were poled radially and ...
An ultrasonic motor using a metal-ceramic composite actuator generating torsional displacement
(Japan J Applied Physics, 1998)
An ultrasonic motor composed of three components; a stator, a rotor and a ball bearing is proposed. The stator is made of an active piezoelectric ring, poled in the thickness direction and bonded with two windmill-like ...
Functional composites for sensors, actuators and transducers
(Elsevier Sci LTD, 1999)
Following the trend in structural applications, composite structures are being used more commonly in transducer applications to improve acoustic, mechanical and electrical performance of piezoelectric devices. Functional ...
