摘要： A phased array ultrasound device includes transducer elements arranged in a two dimensional array; first electrodes, each first electrode extending along a first direction; and second electrodes, each second electrode extending along a second direction, where each transducer element is associated with one first electrode and one second electrode, where each transducer element includes a material located between its associated first electrode and second electrode, and is configured to emit an ultrasonic wave induced by a vibration force or an oscillation force of its material when the transducer element is actuated based on control signals applied to its associated first electrode and second electrode, where each transducer element has a unipolar actuation force direction, and where the phased array ultrasound device is configured to create a pressure focus point by actuating a set of transducer elements to form a combined ultrasonic wave.
