The discussion focuses on optically transparent piezoelectric materials, specifically highlighting quartz as a viable option for converting pressure on touch screens into electrical energy. Participants emphasize the importance of using piezoelectric quartz without metallizing the top layer to harness electrical discharge effectively. Techniques such as printing thin conductive patterns on the surface and coating with resistive materials are suggested to enhance functionality and measure contact position accurately.

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.tenpinfaze said:I was looking for a way to use the piezoelectric quartz without having to metallize the top layer in order to utilize the electrical discharge.
