Graphene-Based Electronic Ink Creates Super-Thin Midi Controllers

There’s been a significant amount of interest swirling around Graphene (a one-atom thick carbon chain) is palpable, and when I see stuff like this, I understand why. Cambridge University has created graphene based-ink that connect to a speaker and circuit. It’s conductive such that when you touch it, it makes noise. Zero-inch thick music controllers/creators? Yes Please!
