International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.This study investigates the synergistic effects of Ti‐doping and K5.4Cu1.3Ta10O29 (KCT) co‐modification on KNN ceramics to develop sustainable, lead‐free piezoelectrics. Co‐modification significantly enhances electromechanical coupling and the mechanical quality factor. The optimized KNN‐Ti‐KCT system achieves thermal stability comparable to commercial

Improved performance of d31-mode needle-actuating transducer with PMN-PT piezocrystal [PDF]
, 2018 Prototypes of a PZT-based ultrasound needle-actuating device have shown the ability to reduce needle penetration force and enhance needle visibility with color Doppler imaging during needle insertion for tissue biopsy and regional anesthesia. However, the demand for smaller, lighter devices and the need for high performance transducers have motivated ...

Design and Characterization of an Ultrasonic Surgical Tool Using d31 PMN-PT Plate
Physics Procedia, 2015 AbstractAn ultrasonic surgical tool for tissue incision and dissection has been designed and characterized. The surgical tool is based on a simple geometry to which PMN-PT d31 plates are bonded directly. The performance of the surgical tool has been defined numerically with the Abaqus finite element analysis (FEA) package and practically with laser ...
