Detect Motion, Shock, and Taps with a Flexible Piezo Film Sensor
The Piezo Vibration Sensor Large is a simple film-based sensor for detecting flex, vibration, taps, impact, and movement. It is a useful part for trigger inputs, motion events, and low-part-count sensing circuits.
As the piezo film moves, it creates an AC signal that can be read with the right conditioning. This large version offers a straightforward way to sense motion without adding a full IMU or accelerometer module.
Important: Piezo sensors can create high voltage spikes during motion. Add the right resistor and protection before feeding the signal into a microcontroller ADC or comparator.
Why you'll love it
- Flexible piezo film sensor: Good for vibration, tap, and shock events
- Large format: Helpful when you want an easy-to-mount sensing strip
- Simple two-wire output: Easy to test with analog or comparator circuits
- Can act like a switch or sensor: Useful for impact alarms and trigger inputs
- No active electronics onboard: Lets you design the front end to match your project
What you can build
Great for knock sensors, vibration alarms, interactive props, impact logging, tamper detection, and simple motion-triggered inputs.
Starter bundles
Pair it with a resistor network, comparator or analog input, and a microcontroller board for threshold-based triggers or analog logging.
Recommended add-ons
Useful add-ons include resistors, protection parts, microcontroller boards, cable leads, and mounting tape or brackets.

Frequently Asked Questions
Can I connect this right to an Arduino pin?
Use the right resistor and protection first. Piezo film can create voltage spikes.
Is this good for knock sensing?
Yes. It works well for taps, knocks, and basic impact detection.
Does it measure direction or full motion data?
No. It is a simple event-style sensor, not a full motion sensor.
