3D Printing Electronics on a Sticker (Video)

3D Printing Electronics on a Sticker– the application of printing technologies for the fabrication of electronic circuits and devices, increasingly on flexible plastic or paper substrates – have been around for a while. Printed electronics has its origins in conductive patterns printed as part of conventional electronics, forming flexible keyboards, antennas and so on. Then came fully printed testers on batteries, electronic skin patches and other devices made entirely by printing, including batteries and displays

Despite its increasing use, printed electronics applications are still challenged in terms of performance, processing costs, and especially complementary metal–oxide–semiconductor (CMOS) industry incompatibility.

For that reason, we wanted to create a new method to print high-performance electronics by combining the extremely mature CMOS fabrication processes and recently developed additive manufacturing techniques,” Muhammad Mustafa Hussain, an Associate Professor of Electrical Engineering at King Abdullah University of Science and Technology (KAUST), tells Nanowerk. “This challenge motivated us to come up with a solution where circuits are not printed starting from sublevel devices (transistors) but instead prints complex CMOS circuits fabricated using the most advanced nanofabrication techniques.
