Abstract

An ultrasonic transducer array including a substrate, a membrane overlying the substrate, the membrane configured to allow movement at ultrasonic frequencies, and a plurality of anchors connected to the substrate and connected to the membrane. The membrane includes a piezoelectric layer, a plurality of first electrodes, and a plurality of second electrodes, wherein each ultrasonic transducer of a plurality of ultrasonic transducers includes at least a first electrode and at least a second electrode. The plurality of anchors includes a first anchor including a first electrical connection for electrically coupling at least one first electrode to control circuitry and a second anchor including a second electrical connection for electrically coupling at least one second electrode. The ultrasonic transducer array could be either a two-dimensional array or a one-dimensional array of ultrasonic transducers.
