Smartphone-Controlled Smart Bandage is Designed to Deliver Multiple
  Medications
From: Rehab Management - 10/09/2017

Researchers from University of Nebraska-Lincoln, Harvard Medical School, and
MIT have designed a smart bandage able to help heal diabetic skin wounds via
a microcontroller triggered by a smartphone or other wireless device.

The bandage consists of electrically conductive fibers coated in a gel that
can be individually loaded with infection-fighting antibiotics,
tissue-regenerating growth factors, painkillers, or other medications.

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 fiber. That voltage heats the fiber and its hydrogel, releasing
whatever cargo it contains, explains a media release from University of
Nebraska-Lincoln.
