甬江实验室团队创制出超级压电陶瓷

Core Viewpoint - The research team at Yongjiang Laboratory has developed a new type of piezoelectric ceramic based on low-cost polycrystalline lead zirconate titanate, achieving a piezoelectric coefficient of up to 6850 pC/N, marking the birth of a new class of "super piezoelectric ceramics" with high performance and engineering potential [1][2]. Group 1: Research Breakthrough - The new piezoelectric material maintains a stable output of d > 6000 pC/N from room temperature to 350 degrees Celsius, and this performance can potentially extend to extremely low or high temperatures [2]. - The innovative "active working mode" allows the material to function effectively even at traditional "death temperatures," overcoming a long-standing limitation in piezoelectric materials [2]. Group 2: Technological Implications - The research is expected to provide critical material support for next-generation micro-robots, cellular-level ultrasound imaging, and high-fidelity tactile interaction [2]. - The active piezoelectric device paradigm is anticipated to have profound implications for the field of functional materials [2].
