An imaging system includes: a transceiver cell for generating a pressure wave and converting an external pressure wave into an electrical signal； and a control unit for controlling an operation of the transceiver cell. The transceiver cell includes: a substrate； at least one membrane suspending from the substrate； and a plurality of transducer elements mounted on the at least one membrane. Each of the plurality of transducer elements has a bottom electrode, a piezoelectric layer on bottom electrode, and at least one top electrode on the piezoelectric layer. Each of the plurality of transducer element generates a bending moment in response to applying an electrical potential across the bottom electrode and the at least one top electrode and develops an electrical charge in response to a bending moment due to the external pressure wave.
