Description: This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.

Comes with solderable crimp pins and a mass attached to the tip. This mass increases the sensitivity to motion.

Features:

  • Flexible PVDF Piezo Polymer Film
  • Wide dynamic range
  • Laminated for higher voltage output
  • 0.1" breadboard friendly leads

  • how sensitive is this? I’m looking at sensing different vibration profiles from a mobile phone?

  • anyone every use these to power a micro-power device?

  • I’m trying to read the motion of something that moves up and down ~1mm at approximately 5 Hz. Can this read that or is there a better sensor on this site? (I tried the FlexSensor but the motion is too small.) Thanks!

  • How does the mass increase the sensitivity of this?

  • how the design circuit for generated voltage from this piezo?…please help me…email me at akina_mstr@yahoo.com

  • how much power can be produce by this piezo? can i directly use this circuit http://www.sparkfun.com/products/9946? i like to use this in my energy harvester.

  • I would like to attached this to large piece of machinery as vibration sensor. Has anyone built anything with this sensor? What was the maximum frequency?

  • I’m using this to power a flashlight abaxas1! All though I’m prototyping I got a successful voltage swing of around 1volt when vibrated very quickly. A joule thief would help get the voltage up for a flashlight/a couple of LEDs!
