Structural Design

● Piezoelectric Stack Core: Multi-layer ceramic stacks integrated with flexure hinges to convert piezoelectric deformation into controlled axial linear displacement (extension/contraction).

● Modular Encapsulation: Stainless steel/titanium housing with preload mechanisms ensures uniform stress distribution, preventing delamination under kHz-level dynamic operations.

● Custom Interfaces: Tailorable end caps, bases, and connectors with coaxial shielded wiring to minimize EMI and enhance signal integrity.

Material Properties

● High-Performance PZT: Modified lead zirconate titanate (PZT)-based material with d33≥600 pC/N, hysteresis <3%, and thermal drift <0.02%/°C for superior electromechanical efficiency.

● Fatigue-Resistant Flexures: Titanium alloy hinges with 0.02N/μm stiffness, >50G shock resistance, and >1×10⁸ cycles in -25°C~130°C environments.

● Low-Loss Electrodes: Ag-Pd alloy electrodes with coaxial shielding (resistivity <0.1Ω·cm) support high-frequency driving with controlled thermal rise.

Core Advantages

● Nanometer-Level Resolution: 0.1nm displacement resolution and <0.15%F.S. repeatability for ultra-precision optical tuning and micromachining.

● High Force Density: Kilonewton-level thrust output with superior stiffness and force density vs. traditional electromagnetic actuators.

● Rapid Dynamics: 80ms full-step response and >125Hz resonance frequency for real-time vibration control and dynamic compensation.

● Environmental Versatility: Optional vacuum-rated versions for stable operation in oil, humidity, or vacuum environments.
