I How does a Point Force Affect a Piezoelectric?

  1. Oct 11, 2016 #1
    So, let's imagine we have a sphere of metal with a piezoelectric film all around the outside of it. If we applied a point force to one area of the sphere, how would the piezoelectric material react? Would it compress or expand at that point, and how can we measure the force based on the response given? If anyone can lead me to an answer or some good resources that would be fantastic. Thanks guys!

    What do you think would happen ?

    I assume it would cause a compression where the force is applied and an expansion just about everywhere else, most significantly at the opposite side of the force

    How is the sphere supported ? How big is it ?

    What metal is the sphere made from ?

    Please post a sketch of the whole arrangement that you have in mind .
