This idea, that bandages can be \"smart,\" is behind a new invention by a team of engineers at Tufts University. \" This diagram illustrates how the smart bandage collects data from a wound, then delivers medication and communicates with a mobile device. Nano Lab, Sameer Sonkusale, Tufts UniversityThe smart bandages have pH and temperature sensors to measure the primary markers of wound healing. The real-time data from the bandage's sensors is read by a microprocessor that can then signal an on-demand antibiotic release, creating a better environment for wounds to heal. The next step for Tufts University's smart bandages is to test them in a clinical setting and see how the concept stacks up against other smart bandages, including one designed in 2017 by researchers at the University of Nebraska that uses a smartphone to deliver medication.
