    Hi shabaz,

    I am planning to use PVDF film to measure the vibration (signal) due to the different type object's surface. Is PVDF film produce the charge when the force applies to the  surface of PVDF film? 

    Thank you.

    Hi Ng,

     

    Absolutely, this is a very good use-case for PVDF. I tried this too, to be able to identify the start position of paper stickers on a strip of peelable tape, and it was picking up vibrations from the rough surface of the paper : )

    I believe (not tried it) that it could identify different objects due to the surface roughness, with some processing of the data.

    I just used a strip of metal attached to act like a stylus (a bit like a record player) but flattened. You can see it in the URL mentioned earlier. Depending on your actual scenario, perhaps you may want to try different materials as a stylus, maybe even exotic things like sapphire or diamond, and some controlled way of moving it or the object, e.g. with a motor. If you're using a motor, you'll probably want something

    high-end to get the smooth motion, or consult with some mechanical engineer since this could be an advanced topic in itself.
