They 3D print the traces with conductive PLA filament directly onto a base plastic sheet, and then vacuum form the whole thing. The filament is happy to deform when heated – it’s printer filament.

Researchers have developed an inexpensive solar cell that can be painted or printed on flexible plastic sheets. "Someday homeowners will even be able to print sheets of these solar cells with ...

The ADC circuits printed by CEA-Liten include more than 100 n- and p-type transistors and a resistive layer on a transparent plastic sheet. The ADC circuit offers a resolution of 4 bits and has a ...
