•Compared to traditional single-layer piezoelectric ceramics, multilayer structures achieve revolutionary breakthroughs through unique laminated designs: they require only tens of volts to operate (compared to hundreds for single-layer) while delivering greater displacement (millimeter-scale) and stronger thrust (thousands of newtons). Their thin-layer structure enables sub-millisecond rapid response and higher energy efficiency, making them ideal for high-frequency precision control applications. Additionally, the multilayer co-firing process significantly enhances device reliability, with a service life of up to hundreds of millions of cycles. They also excel in miniaturization, reducing volume by over 50% for equivalent performance.
