概要
- 論文の詳細を見る
The impulse response characteristics of polymer ultrasonic transducers were analyzed using the Mason's equivalent circuit. These characteristics strongly depend on material factors of the piezoelectric polymer; the dielectric and mechanical internal loss factors, the electromechanical coupling factor and the acoustic impedance. Based on the analytical results, we evaluated the piezoelectric polymers that are presently available as transducing materials. The analytical results were verified experimentally using transducers composed of poly(vinylidene-fluoride) film and vinylidene fluoride and trifluoroethylene copolymer film.
