Intelligent bandages can heal your body

A new ‘smart’ bandage is capable of dispensing multiple medications when triggered by a mobile device. Developed by researchers from the University of Nebraska-lincoln, Harvard Medical School and MIT, the bandage consists of fibres coated in a gel that house anything from antibiotics to painkillers. When a small amount of voltage is applied, the fibre and its gel heat up, releasing the drugs. Further testing is needed, but it’s hoped the bandage will eventually heal chronic wounds and battlefield injuries.
