Smart sensors for bandages

Scientists are developing smart sensors which can monitor the healing progress of a wound, eliminating the need to look underneath a bandage.

The sensors detect wound healing by monitoring microscale changes in the body’s tissue. 

The research group, led by Heriot-Watt University in Edinburgh Assistant Professor Dr Michael Crichton, has been awarded £360,000 from the Engineering and Physical Sciences Research Council.

Research in the field has traditionally focused on the biological properties of wounds, but knowledge about the mechanics of how they heal is limited, especially at the microscale where changes happen at sub-hair width scales.

Crichton and his team intend for the final form of the sensor to be embeddable within a bandage to measure changes in a wound’s properties without interfering with the process, making small mechanical measurements to see how the tissue is changing.
