Freestanding Hierarchical-Porous BCZT Thin Films Enable Efficient Ultrasonic Energy Harvesting in Soft Tissue. [PDF]

Adv Sci (Weinh)
Freestanding hierarchical‐porous BCZT thin films integrate a compliant porous surface with a dense piezoceramic backbone to balance mechanical reliability, voltage sensitivity, and acoustic coupling. The films enable stable wearable pulse‐wave monitoring and enhanced tissue‐coupled ultrasonic energy harvesting, offering a promising route toward soft ...
