Has anyone ever tried this?

The problem is that they have no connectors. Just bare ITO traces, which have an oddball spacing of 1.15mm.

A combination of heat and pressure would bond the flex connector to the ITO and conductive particles would be trapped between the copper and ITO connectors. Another experiment to perform.
