Piezo-electric PVDF Disk Metallized with Copper-Nickel

Metallized Piezo-electric PVDF Disk provides the piezoelectric sensitivity and chemical resistance of PVDF with a thin metallic electrode layer, fabricated into a precise circular form for direct integration into compact sensing, actuation, or transduction devices. Industries use these discs for medical ultrasound probes, tactile sensor arrays, and impact monitoring devices. Specific applications include miniature ultrasonic emitters, haptic feedback elements in control systems, and vibration monitoring in high-value rotating machinery. In research, they are used to study device miniaturization, improve electrode-PVDF adhesion, and optimize piezoelectric output in constrained geometries. The combination of controlled shape, metallized functionality, and PVDF’s durability ensures suitability for advanced sensing and electromechanical innovation.
