Higher Motion Sensitivity with a Weighted Piezo Vibration Sensor
The Piezo Vibration Sensor Large with Mass is a flexible piezo film sensor built for vibration, motion, tap, and shock detection. The added tip mass improves sensitivity to motion, which makes it a strong choice for event-triggered sensing.
Like other piezo film sensors, it creates an AC signal when the film bends or moves. This version adds a mounted mass so smaller movements can produce a stronger response.
Important: This sensor can generate large voltage spikes when moved. Use a resistor network and proper input protection before feeding the signal into an ADC or comparator.
Why you'll love it
- Mass-loaded piezo tip: Increases sensitivity to motion
- Flexible PVDF piezo film: Good for vibration and shock sensing
- Wide dynamic range: Useful across light to stronger motion events
- Laminated film design: Helps produce stronger voltage output
- Breadboard-friendly leads: Easy to prototype in test circuits
What you can build
Use it in motion-triggered props, knock detectors, condition monitoring tests, tamper alerts, vibration logging, and simple energy-harvest or event detection experiments.
Starter bundles
Pair it with a resistor network, microcontroller, or comparator board to turn raw vibration into a clean event signal.
Recommended add-ons
Helpful add-ons include resistor kits, signal conditioning boards, microcontrollers, data loggers, and mounting hardware.

Frequently Asked Questions
What does the added mass do?
It makes the sensor more sensitive to movement and vibration.
Can it be used as a simple switch?
Yes. With the right circuit, it can act like a motion or impact trigger.
Do I need protection parts?
Yes. Piezo sensors can create spikes, so protect your input stage.
