Abstract:

A multi-layer composite transducer array includes at least one pair of composite transducers with an electrical and mechanical isolation layer disposed there between. Each composite transducer is defined by a composite panel having a common electrode coupled to a first surface and electrode segments electrically isolated from one another and coupled to a second surface. Each pair of composite transducers is configured such that the electrode segments associated with the pairs composite transducers oppose and are aligned with one another. The isolation layer has dielectric material segments that are sized, shaped and aligned in correspondence with opposing and aligned ones of the electrode segments associated with the pairs transducers. Spaces formed in the isolation layer between the dielectric material segments are filled with a viscoelastic material.
