A Swiss research team revealed a big step in the field of bendable circuits. They made a super-thin circuit that can function while wrapped around a human hair. It can even be laid on a contact lens.

The team at Swiss Federal Institute of Technology created a circuit on a parylene film just a single micrometer thick, making it one sixtieth the thickness of a human hair. They achieved this feat by building the circuit on a vinyl polymer base that dissolves away to leave an ultra thin and ultra flexible circuit intact.

The most immediate application for this would be to create a transparent circuit on a contact lens to sense the increased pressure in the eye that causes glaucoma. Will this also pave the way to more medical applications? And maybe Google Glass in your contact lens one day?
