Multiplexed Cutaneous Wound Monitor for Point‐of‐Care Applications

Wearable wound health monitors can radically revolutionize the methods of contemporary wound care monitoring, thereby greatly reducing the burden on the healthcare system. By integrating sensors that can monitor parameters of the wound bed and interfacing them with wireless capabilities, continuous and remote monitoring can be achieved. The focus of this work is to demonstrate a system‐on‐chip, multiplexed wound healing monitor on a flexible wireless platform. A triangulated approach of measuring CRP, IL‐6 proteins, pH, and temperature is used to wirelessly track changes in parameters that indicate the progress or lack thereof of wound healing. Further, to mimic functionality on skin conditions, the dependency of biomarkers and pH responses with temperature has been investigated. These systems can find imminent applications in clinical point‐of‐care diagnostics.
