Grade: Piezo-electric
Composition: PVDF
Form: Disk
Material: Polyvinylidene fluoride (PVDF)
CAS Number: 24937-79-9
Commodity: Polymers
Orientation:
Uni-axially Oriented
Piezo-Electric PVDF Disk combines lightweight flexibility with excellent piezoelectric and pyroelectric properties, making it a key material in sensors, actuators, and energy harvesting devices. The disk form offers uniform thickness and defined geometry for integration into precision assemblies such as acoustic pickups, ultrasonic transducers, and vibration monitoring systems. Industries use it in structural health monitoring, medical imaging, and tactile sensing technologies. Research applications include thin-film microphone diaphragms, dynamic strain gauges, and low-power vibration energy harvesters. PVDF’s unique combination of mechanical flexibility, dielectric strength, and responsiveness to stress and temperature changes makes the disk form indispensable in both applied engineering and experimental designs requiring compact, sensitive transduction elements.
