High-frequency ultrasonic transducer based on lead-free BSZT piezoceramics
Ultrasonics, 2011This paper describes the fabrication and evaluation of a high-frequency (40MHz) transducer based on lead-free piezoceramics for ultrasonic imaging. The transducer with an aperture size of 0.9mm has been fabricated using barium strontium zirconate titanate ((Ba(0.95)Sr(0.05))(Zr(0.05)Ti(0.95))O(3), abbreviated as BSZT) ceramics. The lead-free BSZT has a

Design of actively tuned flexural piezoceramic bar/disk transducers
The Journal of the Acoustical Society of America, 2000Underwater transducers with variable and controllable resonance frequency can efficiently transmit stepped or linear chirp signals of greater bandwidth by continuously matching their resonance frequency to the dominant frequency of the transmitted signal.

The electromechanical feed-back in piezoceramic sensors and transducers
1998 IEEE Ultrasonics Symposium. Proceedings (Cat. No. 98CH36102), 2002The possibility is shown of control of the characteristics of piezoelectric transducers with the help of a spatial electromechanical feed-back. It is shown that under certain conditions, the error of transducers can theoretically be reduced to zero.

Optimum Damping of Beam Vibrations Using Piezoceramic Transducers
2016In this thesis a piezo-electro-mechanical system, constituted of an aluminum beam with five piezoelectric patches glued on it, each of them shunted with an RL electrical circuit, has been numerically and experimentally investigated, in order to determine the optimal electric tuning parameters for vibration damping.
