title: High-frequency piezopolymer transducers with a copper-clad polyimide backing layer.
abstract: The effect of a copper-clad polyimide (CCP) backing layer on piezopolymer transducer performance is evaluated. High-frequency, spherically curved polyvinylidene fluoride (PVDF) transducers with and without a CCP backing layer are electrically and acoustically tested. The results showed very similar operating characteristics. B-mode in vivo images of a mouse embryo also showed no qualitative differences, indicating that the CCP backing layer does not affect transducer performance.
