Abstract | |||||||||||
| A class IV flextensional device based on electrostrictive P(VDF-TrFE) copolymers was fabricated and characterized. As an actuator,an produce a displacement of more than 1 mm in air with high load capability. As an underwater transducer the device can be operated at frequencies of several kilohertz with high transmitting voltage response and low mechanical quality factor. Finite element analysis was used to model the flextensional device. The modeling indicates that the performance of the flextensional transducer could be readily tailored by adjusting the parameters of the flextensional metal shell to meet the requirement of different applications..
