About

Cheng Che Tsai is a leading researcher in advanced piezoelectric materials and sensor technology, with a particular focus on lead-free ceramics for high-performance accelerometers. His most cited work, "The Design and Fabrication of Shear-Mode Piezoelectric Accelerometers with High Bandwidth Using High Piezoelectric g-Coefficient NKN-Based Ceramics," demonstrates his expertise in developing environmentally friendly alternatives to traditional lead-based piezoelectrics. Tsai's major contribution lies in optimizing (Na0.475K0.475Li0.05)NbO3 (NKLN) ceramics through ZnO doping, achieving enhanced piezoelectric g-coefficients that are critical for sensor sensitivity. By systematically investigating ZnO concentrations from 0 to 0.3 wt.%, he established processing-structure-property relationships that enable the fabrication of shear-mode accelerometers with exceptional bandwidth—a breakthrough for applications requiring precise, high-frequency vibration measurement. His work addresses the growing demand for sustainable sensor technologies without compromising performance, positioning him at the forefront of lead-free piezoelectric research. With 2 citations to date, his findings are gaining traction in the fields of structural health monitoring, aerospace, and industrial automation. Tsai's research exemplifies how materials innovation can drive practical engineering solutions, making him a notable figure in the transition toward greener electronic components.
