“…In addition, the aim of element doping is to have good thermal stability and high piezoelectric performance concurrently. The motivation for selecting Yb as the doping element is that (i) the ionic radius of Yb 3+ (0.87 Å) is very close to the ionic radius of Sm 3+ (0.96 Å) because the Sm 3+ -doped crystal showed record-high piezoelectric properties ( 27 ) and (ii) a quantitative analysis of a Yb doped for PIN-PMN-PT piezoelectric crystal has yet to be reported ( 37 , 38 ). The motivation for selecting Bi as the co-doped element is that Bi can prevent the decrease of T c ( 39 ).…”

Ultrasound is widely used for tissue imaging such as breast cancer diagnosis; however, fundamental challenges limit its integration with wearable technologies, namely, imaging over large-area curvilinear organs. We introduced a wearable, conformable ultrasound breast patch (cUSBr-Patch) that enables standardized and reproducible image acquisition over the entire breast with less reliance on operator training and applied transducer compression. A nature-inspired honeycomb-shaped patch combined with a phased array is guided by an easy-to-operate tracker that provides for large-area, deep scanning, and multiangle breast imaging capability. The in vitro studies and clinical trials reveal that the array using a piezoelectric crystal [Yb/Bi-Pb(In 1 /2 Nb 1/2 )O 3 -Pb(Mg 1/ 3 Nb 2/3 )O 3 -PbTiO 3 ] (Yb/Bi-PIN-PMN-PT) exhibits a sufficient contrast resolution (~3 dB) and axial/lateral resolutions of 0.25/1.0 mm at 30 mm depth, allowing the observation of small cysts (~0.3 cm) in the breast. This research develops a first-of-its-kind ultrasound technology for breast tissue scanning and imaging that offers a noninvasive method for tracking real-time dynamic changes of soft tissue.
