Scientists develop smart bandage for better and faster healing

The bandage, developed by researchers from the University of Nebraska-Lincoln, Harvard Medical School and Massachusetts Institute of Technology in the US, consists of electrically conductive fibres coated in a gel. The gel can be individually loaded with infection- fighting antibiotics, tissue-regenerating growth factors, painkillers or other medications, researchers said.

A microcontroller no larger than a postage stamp, which could be triggered by a smartphone or other wireless device, sends small amounts of voltage through a chosen fibre. That voltage heats the fibre and its hydrogel, releasing whatever cargo it contains.A single bandage could accommodate multiple medications tailored to a specific type of wound, researchers said.

While offering the ability to precisely control the dose and delivery schedule of those medications. That combination of customisation and control could substantially improve or accelerate the healing process, said Ali Tamayol, assistant professor at University of Nebraska-Lincoln.

"That is a big advantage in comparison with other systems. What we did here was come up with a strategy for building a bandage from the bottom up," Tamayol said.
