Square Multi-Layer Stack Piezoelectric Ceramic

Redefining the boundaries of precision actuation and sensing technology through innovative structural design, superior material properties, and rigorous manufacturing standards. As a professional piezoelectric ceramic manufacturer, we empower clients via full-process technological integration, delivering highly reliable and high-performance customized solutions to advance cutting-edge applications.

Structural Design

● Multi-Layer Stack Architecture: Dozens to hundreds of ultra-thin piezoelectric ceramic layers are stacked with alternating internal electrode polarization, significantly enhancing axial displacement and force output while maintaining compact dimensions.

● Square-Optimized Structure: Square cross-section design improves mechanical stability for parallel grouping or array configurations. Symmetrical structure reduces thermal stress while enhancing heat dissipation and long-term reliability.

● Precision Encapsulation: High-temperature-resistant insulation materials with built-in preload adjustment ensure uniform stress distribution across layers, preventing delamination and supporting high-frequency dynamic operations.

Material Properties

● High-Performance Piezoelectric Ceramic: Modified lead zirconate titanate (PZT)-based materials with high Curie temperature, exceptional piezoelectric constant (d33≥600 pC/N), and superior electromechanical coupling coefficients enable efficient energy conversion.

● Thermal Stability: Optimized doping and sintering processes ensure stable performance across a broad temperature range (-25°C to 130°C) with minimal drift, guaranteeing consistent output in harsh environments.

● Low Loss Characteristics: Low dielectric loss (tanδ＜1.5%) and mechanical loss support kHz-level driving frequencies, reducing heat generation and extending operational lifespan.

Core Advantages

● High Force Density: Multi-layer structure generates hundreds of Newtons of thrust under low voltage (≤200V), far exceeding conventional single-layer ceramics.

● Sub-Nanometer Precision: Displacement resolution reaches sub-nanometer levels with repeatability <0.1%, meeting ultra-precision positioning demands.

● Millisecond Response: Electromechanical response time as low as microseconds, suitable for high-frequency dynamic adjustments and real-time feedback systems.

● Extended Lifespan: Full-density ceramic structure without adhesive layers ensures high fatigue resistance, cycle life >10^8, and 24/7 continuous operation.

Typical Applications

● Semiconductor Manufacturing: Mask stage micro-motion correction, wafer probe station precision alignment.

● Optical Instruments: Adaptive optics mirror actuation, laser beam stabilization, and focus control.

● Medical Devices: Ultrasonic scalpel transducers, endoscopic micro-drive modules.
