Patent ID: 11917921

Abstract:
A flexoelectricity ultrasonic (UT) transducer imaging system is disclosed comprising a polytetrafluoroethylene (PTFE) layer, a plurality of flexoelectricity UT transducers, and a multiplexer. The PTFE layer includes a front and back surface and the plurality of flexoelectricity UT transducers is attached to the back surface of the PTFE layer. Each UT transducer has a front-end and back-end and the front-end of each flexoelectricity UT transducer is attached to the back surface of the PTFE layer. The flexoelectricity UT transducers are arranged along the back surface of the PTFE layer as a two-dimensional array and each flexoelectricity UT transducer is configured to vibrate in a normal direction to the back surface of the PTFE layer. The multiplexer in signal communication with each flexoelectricity UT transducer, where the flexoelectricity UT transducers are sandwiched between the multiplexer and the PTFE layer.
