This stretchy, drug-delivering gel could be the Band-Aid of the future

Researchers in the US have developed a sticky, stretchable gel-like material that can be used as a “smart wound dressing”. Incorporating temperature sensors and drug reservoirs, the hydrogel bandage can release medicine in response to changes in skin temperature, and embedded LEDs even light up to let you know when your meds are running low.

The hydrogel matrix that makes up the dressing has numerous advantages over conventional cloth-based bandages. It’s highly flexible and stretches easily so can be applied to any area of the body, including joints like elbows or knees.
