Researchers at Nanyang Technological University in Singapore (NTU) have successfully printed complex electronic circuits using a t-shirt printer. They were printed using in layers on flexible stuff like paper or plastic and included resistors, transistors and capacitors. All were printed using non-toxic organic materials like silver nanoparticles, carbon and plastics.

The types of complex circuits the team has successfully printed include a 4-bit DAC, and an RFID. Not all that complex, sure, but a great proof-of-concept.

Associate Professor Joseph Chang is the leader of the NTU Singapore research group behind this. I couldn’t find the relevant paper for homework, but I did find this photo.circuit on a sheet
