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.

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.

Technical specifications

Pinout & usage notes

This is a two-wire passive sensor. The added mass raises motion sensitivity, so plan input protection and threshold tuning around your use case.
