Abstract

An ultrasonic transducer device has an acoustic layer with a two-dimensional array of acoustically active elements, a first electrode layer on a first side of the acoustic layer and a second electrode layer on a second side of the acoustic layer. The first electrode layer and the second electrode layer have non-parallel electrodes that permit each acoustically active element in the two-dimensional array to be separately addressable by a controller. A series of kerfs separate adjacent acoustically active elements in the two-dimensional array of acoustically active elements of acoustically active elements, the series of kerfs being filled with a low dielectric, low acoustic impedance filler.
