Smart Bandage

Imagine a bandage with embedded sensors that detects and transmits conditions of wound healing. That’s one form of a smart bandage, and one of the engineering feats that make that conceivable is micro-transistors that can be adhered to a plastic substrate and function properly while sticking to some part of a human’s body.  Researchers at Georgia Tech have improved the concept with their discovery of a bilayer dielectric (i.e. two non-conducting materials that insulate a pair of conductors), making a better transistor.  Most electronic “bandages” work by detecting oxygen in the blood of a damaged tissue region.    MORE
