MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202418027401 A) filed by Exo Imaging Inc. on April 02, 2024, for Imaging Devices Having Piezoelectric Transducers.
Inventors include Akkaraju, Sandeep; Kwon, Haesung; Haque, Yusuf; and Bryzek, Janusz.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: An imaging system (120) includes: a transceiver cell (210) for generating a pressure wave and converting an external pressure wave into an electrical signal; and a control unit (208) for controlling an operation of the transceiver cell (210). The transceiver cell (210) includes: a substrate (501); at least one membrane (504) suspending from the substrate (501); and a plurality of transducer elements (520) mounted on the at least one membrane. Each of the plurality of transducer elements (520) has a bottom electrode (806), a piezoelectric layer (804) on bottom electrode (806), and at least one top electrode (802) on the piezoelectric layer (804). Each of the plurality of transducer elements (520) generates a bending moment in response to applying an electrical potential across the bottom electrode (806) and the at least one top electrode (802) and develops an electrical charge in response to a bending moment due to the external pressure wave.
