Australian researchers have developed a fibre that changes colour in response to temperature with the aim of creating a smart bandage that can indicate the state of underlying wounds and warn of infection. With the ability to show temperature changes of less than 0.5 of a degree Celsius, the smart bandage would allow for easier and faster identification of healing problems that are typically accompanied by an increase or decrease in local temperature, such as infection or interruptions to blood supply. Lead inventor of the colour-changing fibre, Louise van der Werff, a CSIRO materials scientist and Monash University PhD student, says that weaving the fibre into a bandage will allow clinicians to determine the temperature across the wound and surrounding tissue. By comparing the colour of the fibres with a calibrated chart, the clinicians will be able to quickly determine the health of the wound. GM
