Optically Transparent Piezoelectric Materials

  1. Apr 29, 2016 #1
    Does anyone know of any optically transparent (and preferably thin) piezoelectric materials I could use for a science fair project converting pressure on the glass of touch screens to electrical energy?

    Surfaces can be conductive and transparent. The voltage signal produced by quartz has a very low current. That means you can print many thin conductive patterns on the surface that measures the position of the contact.

    Another way is to coat the entire back and front surfaces with a very thin resistive material. Ground the front edges, but make connections to the back left and right, top and bottom edges. Touching the surface will produce currents at two opposite edges that are proportional to position between those edges.
