Wound infections pose a significant threat to patient health by delaying healing, increasing treatment costs, and potentially leading to severe complications such as chronic wounds and sepsis. Current diagnostic methods depend on visible symptoms or laboratory tests, which are invasive, time-consuming, and inconvenient. To address these limitations, this project introduces InfecSense, a smart colour-changing diagnostic patch designed for the early detection of wound infections. The patch utilizes pH- and biomarker- sensitive materials that respond to biochemical changes associated with bacterial activity, producing a visible colour shift that alerts patients and caregivers in real time. The system is non-invasive, portable, and cost-effective, making it suitable for both clinical and home-care settings, especially for patients requiring continuous monitoring. By enabling early detection, InfecSense reduces reliance on hospitalization, promotes timely medical intervention, and improves overall patient outcomes. Future advancements will focus on integrating electronic sensors and artificial intelligence to enhance accuracy and extend the patch’s applications to chronic and post- surgical wound management.
