Technical Overview

1. Material & Design

This piezoelectric sheet is fabricated from PZT-5A, a soft piezoelectric ceramic material known for its high piezoelectric coefficients, stable dielectric properties, and excellent electromechanical coupling efficiency. The 5x5x2 mm form factor is optimized for integration into compact devices requiring precise positioning or force sensing. Controlled sintering protocols and domain orientation processes ensure consistent performance across each substrate.

2. Key Performance Characteristics

• Displacement (31.9 μm ±15%): Provides precise mechanical movement under 200V applied voltage, suitable for micro-positioning applications.
• Capacitance (80 nF ±15%): Stable electrical characteristics ensure predictable charge storage and power consumption.
• Resonant Frequency (>500 kHz ±20%): High resonant frequency enables fast response times for dynamic actuation and sensing.
• Stiffness (400 N/μm ±20%): High mechanical stiffness provides reliable force transmission and positional stability.
• Blocking Force (800 N ±20%): Capable of generating substantial force at blocked condition, suitable for clamping and holding applications.

3. Primary Applications

• Precision Actuators: Micro-positioning stages, fast switching devices, and precision alignment mechanisms requiring accurate mechanical response.
• Sensors & Vibration Monitoring: Vibration detection systems, accelerometers, and force sensors leveraging stable dielectric properties.
• Automated Control Assemblies: Micro-movement control in manufacturing equipment, robotic systems, and precision assembly lines.
• Research & Development: Experimental setups for piezoelectric phenomena studies, calibration standards for sensor development labs.
• Medical Devices: Precision fluid dispensing, ultrasonic cleaning, and micro-pumping applications.

4. Performance Considerations

• Voltage Range: Optimized for 200V operation. Higher voltages may increase displacement but risk depolarization or dielectric breakdown.
• Temperature Sensitivity: PZT-5A properties vary with temperature. Operating within specified temperature range ensures stable performance.
• Mechanical Preload: Application of moderate mechanical preload can enhance displacement and reduce tensile stress during operation.
• Drive Mode: Suitable for both static (DC) and dynamic (AC) operation. For dynamic applications, stay below resonant frequency for stable control.

Quality Assurance

• Phase Purity Verification: XRD analysis confirms the desired perovskite phase and detects secondary phases.
• Microstructure Control: Controlled sintering ensures uniform grain size and minimal porosity for consistent performance.
• Electrical Testing: Capacitance, displacement, and blocking force measured for each batch to verify specifications.
• Surface Finish Assessment: Ensures proper electrode adhesion and minimizes surface defects.
• Poling Verification: Domain orientation confirmed through piezoelectric coefficient measurement.

Handling & Storage

• Store in a controlled, low-humidity environment to maintain material integrity.
• Handle with care to avoid mechanical shock or excessive bending which may cause cracking.
• Use anti-static precautions during handling to prevent electrostatic discharge damage.
• Avoid exceeding specified voltage limits to prevent depolarization or dielectric breakdown.
• Keep electrodes clean for reliable electrical connection.
