A PhD student from Melbourne, Australia, has created the ultimate minor medical tool for mums. It's a bandage that monitors the health of a cut and lets you know when it's infected.
The bandage is the brainchild of Louise van der Werff, a PhD student at Monash University in Melbourne, Australia. She developed a temperature sensitive fabric that can be weaved into a bandage or a roll of medical dressing. When you wrap a wound, the dressing will change colours when an infected wound gets warm. Forget poking and prodding for pus, all you have to do is wait for a colour change.
