This basic piezo sensor 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. Simply because adding mass increases the sensor interia and therfore vibration amplitude. Increasing the vibration amplitude will increase the signal level and sensitivity
