Printable, foldable electronics demonstrated.
A Northwestern University team has developed a graphene based ink that is highly conductive and tolerant to bending, with the ink’s conductivity remaining virtually unchanged even when folded.
The team has demonstrated how the ink can be used in inkjet printers to allow for low cost printable electronics, which could also be scaled up to larger sizes reasonably easily.
Inkjet printing has previously been explored as a method for fabricating transistors, solar cells, and other electronic components. It is inexpensive, capable of printing large areas, and can create patterns on a variety of substrates, making it an attractive option for next-generation electronics.
