Graphene-based Ink developed by Scientists at Cambridge

Ink has been around for ages and has been traced all the way back to the 23rd century. While it comes in a variety of colors, it’s a low-tech material, but that’s about to change thanks to a new substance by the name of Graphene Ink.

Researchers at the University of Cambridge in collaboration with Novalia Limited used graphene-based ink to print a small playable keyboard. The keys are printed with Graphene Ink and placed over electrodes that are connected to a circuit and a speaker. As the ink is conductive, when someone touches a key a change in the electric charge is detected and sent to the circuit which allows the speaker to play the note. You can witness the keyboard in action below…

The keyboard is just one example of how Graphene Ink can be used, and while it’s cool, the flexible digital display really grabbed our attention. The display and was built by the same Cambridge team along with Printed Electronics Limited. The display pops up around the 47 second mark, and shows a digital display that’s been printed on a thin, bendable piece of plastic. Impressed? We’ve heard a lot about bendable electronics lately, and the ability to cheaply print digital displays on wafer-thin material cheaply could truly be a game changer for wearable tech.graphene ink

Whether you want to play piano on a piece of cardboard or have a flexible digital display embedded into your clothing, Graphene Ink looks to be an exciting emerging technology to take note of. Heart monitors could be printed and placed into clothing, but the possibilities are endless when you think about it. The low cost of Graphene Ink compared to similar conductive inks (silver, copper) will hopefully help get this tech fast-tracked so that we’ll see it in new products sooner rather than later.
