Smart Textile Communicates Wound Health

One of the biggest benefits of smart materials is their ability to diagnose and communicate important changes in their environment. One compelling application is a smart bandage that reveals the state of the wound it protects. Developed by materials scientists at Australia’s Monash University and CSIRO, the bandage is made of thermochromic fiber that changes color in response to wound temperature.
“We’ve created a fabric that changes color in response to temperature—showing changes of less than 0.5 of a degree,” says Monash lead inventor Louise van der Werff. “We expect that, when incorporated into a bandage it will allow nurses to quickly identify healing problems such as infection or interruptions to the blood supply, which are typically accompanied by a local increase or decrease in temperature.”
The technology will be developed for commercial use in six months, at which time it will be initially targeted for chronic wound patients.
