How the Piezo PVDF Energy Harvester Works
The Piezo PVDF Energy Harvester operates by converting mechanical vibrations into electrical energy using the piezoelectric effect. When the PVDF film bends or vibrates, it generates a charge due to its unique crystalline structure, enabling efficient power generation for low-energy electronics and sensors.
At Peraglobe Technologies, we’re proud to partner with PolyK ,USA advanced material manufacturers to bring these innovations to applications in aerospace, defense, energy, and industrial automation.
What Makes the Firefly Device Special
The Firefly model employs high-performance PVDF film with silver-ink electrodes, featuring approximately 730 pF capacitance and an active area of 57 × 15 mm. With this configuration, the film can generate over 100 V from vibrations — enough to light a neon bulb. piezopvdf.com
Thanks to the robust PVDF film thickness (about 120 µm) and high d₃₁ coefficient, the device combines durability with high output, making it ideal for integration in compact, flexible systems.
Ideal Applications & Use-Cases
Wearable electronics powered by body motion (walking, running)
Self-powered wireless sensors in structural health monitoring
Low-power IoT devices in remote or mobile applications
Energy-capture modules in smart textiles, shoes, backpacks
Design & Integration Considerations
For optimal performance, consider:
Active area sizing — larger films yield higher charge generation.
Mechanical interface — correct bending or extension ensures efficient conversion.
Circuit matching — proper energy-capture and storage electronics convert high-voltage pulses into usable DC levels.
Packaging — ensure environmental protection and mechanical coupling for reliability.
