A flexible piezo vibration sensor from Measurement Specialties, commonly used for detecting flex, touch, vibration, and shock. The PVDF polymer film generates a small AC voltage (up to ±90 V) when it moves, which can be brought down to ADC-readable levels with a simple resistor divider. This version includes a mass attached to the tip for increased motion sensitivity.
Key Features
- PVDF Piezo Polymer Film – Flexible sensing element for vibration and impact detection
- Laminated Construction – Higher voltage output for improved sensitivity
- Wide Dynamic Range – Suitable for subtle vibrations through to strong impacts
- Weighted Tip – Attached mass increases sensitivity to motion
- Breadboard Friendly – 0.1″ (2.54 mm) pitch leads with solderable crimp pins
Ideal For
- Vibration and shock detection
- Impact sensing and tap detection
- Flexible switch applications
- Arduino and microcontroller analogue input projects
Package Contents
- 1× Piezo Vibration Sensor (large, with mass)
- Solderable crimp pins

Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- dynamic range
- Dynamic range describes how wide a span of values a sensor can measure, from very low to very high. For a light sensor, a wide dynamic range means it can work in dim indoor settings as well as bright sunlight without changing hardware.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
