The piezoelectric effect arises from the asymmetric arrangement of atoms in certain crystalline ... Piezoelectric crystals are the core components of ultrasonic transducers, which generate and detect ...

That's because the piezoelectric materials used for sonar and ultrasound applications are mostly ferroelectric. And like all ferroelectric materials, they exhibit a phenomenon called spontaneous ...

Dr. Lewin’s current interests are primarily in the field of biomedical ultrasonics including the design and testing of piezoelectric transducers and sensors, power ultrasonics, ultrasonic exposimetry, ...

The patch is made of a silicone elastomer that houses an array of small piezoelectric transducers sandwiched between stretchable copper electrodes. The transducers transmit and receive ultrasound ...
