A Band-Aid may never be the same again; engineers from the Massachusetts Institute of Technology have come up with the latest model of stick-on dressing: 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 medication as needed, in response to changes in skin temperature. It can even light up if the medication supply is running low.
