Engineering Minute – Flexible Ultrasound Patch

Flexible Ultrasound Patch Allows Imaging Of Odd Shaped Structures

Researchers at UC San Diego have developed a flexible ultrasound patch for use in imaging odd shaped structures, such as machine and building parts, which are normally difficult to image using conventional ultrasound techniques. The thin patch is made of silicone elastomer and an "island-bridge" structure patterned on the surface. The "islands" contain electrodes and piezoelectric transducers which produce ultrasound waves when electricity passes through them. The "bridge" made up of spring-shaped copper wires allows the patch to stretch and bend to conform to any surface. Read more about the flexible ultrasound patch at UC San Diego.
