Using Piezoelectric Film to Capture Voltage
Abstract:
Piezoelectric Film is an enabling transducer technology with unique capabilities. Piezoelectric Film produces voltage in proportion to compressive or tensile mechanical stress or strain, making it an ideal dynamic strain gage. It makes a highly reliable, low-cost vibration sensor, accelerometer or dynamic switch element. Piezo Film is also ideally suited for high fidelity transducers operating throughout the high audio (>1kHz) and ultrasonic (up to 100MHz) ranges. The Piezoelectric Film can become a power source that can be used to power another device. By flexing the PVDF film a voltage is created, that voltage can then be captured and stored until needed.
