Gravity Flexible Piezo Film Vibration Sensor

This flexible Piezo Film Vibration Sensor is perfect for measuring vibrations, bends, impacts, and touches. The sensor is based on a piezoelectric polymer film and comes with a converter board, making it a versatile tool for a wide range of applications. The piezoelectric film is made of a 28 µm thick PVDF polymer, printed with silver-containing electrodes, and laminated on a polyester substrate. When deformed, the film generates high voltages of up to ±90V, allowing it to be used as a flexible switch. Thanks to the universal Gravity interface, integration into projects is easy and quick. The sensor offers both analog and digital output signals and features an integrated potentiometer for adjusting sensitivity. With a wide dynamic range from 0.001 Hz to 1000 MHz, it delivers precise measurement results, even for minor vibrations. The sensor is robust and operates reliably in a temperature range of 0 °C to 85 °C.
