It's miles possible to acquire piezo factors with out a plastic housing. Those will appear like a metallic disc, and are less difficult to apply as enter sensors. Piezo sensors paintings quality whilst firmly pressed against, taped, or glued their sensing floor.

A piezo is an electronic tool that generates a voltage while it is physically deformed by means of a vibration, sound wave, or mechanical stress. In addition, when you put a voltage across a piezo, it vibrates and creates a tone. Piezos can be used both to play tones and to locate tones.
