Water-based “Band-Aid” senses temperature, lights up, and delivers medicine to the skin.

MIT engineers have designed what may be the bandaid of the future: a sticky, stretchy, gel-like material that can incorporate temperature sensors, LED lights, and other electronics, as well as tiny, drug-delivering reservoirs and channels. The “smart wound dressing” releases medicine in response to changes in skin temperature and can be designed to light up if, say, medicine is running low.
