A team of researchers led by the Universitat Rovira i Virgili (URV) has developed an innovative smart bandage that continuously monitors skin temperature without the need for external power sources. This breakthrough device, recently published in Advanced Science, uses a flexible thermoelectric system capable of detecting thermal variations that signal inflammation or infection—key indicators for wound healing.
Developed in collaboration with the University of Porto, the smart bandage leverages thermoelectric materials and conductive polymers, printed using techniques similar to screen-printing. Its grid-like network of thermocouples creates a thermal map of the skin, accurately identifying hotspots with a sensitivity as fine as 0.4°C and a response time under three seconds.
Unlike traditional infrared cameras or spot sensors, this bandage adapts to the skin’s surface, remains functional under sweat or movement, and requires no batteries. Tests have confirmed its durability, surviving hundreds of bending cycles while maintaining accuracy.
The sensor’s output is easily interpreted through a color gradient map, enabling healthcare professionals to make swift, informed decisions without extensive training. With performance comparable to conventional bandages, the device can be worn for several days and opens the door to broader clinical applications.
Future developments aim to integrate additional biosensors, making this technology a powerful tool for personalized and preventive healthcare.
