A team of researchers led by Professor Wei Gao of Caltech has achieved a major milestone in wound care technology with the development of an advanced smart bandage known as iCares. Designed to function like a "lab on skin," this innovative bandage not only monitors chronic wounds in real time but also supports healing through the intelligent application of treatment.
Building on their earlier success with animal trials in 2023, Gao and his collaborators from the Keck School of Medicine at USC have now validated the updated iCares system in a clinical setting. In a recent study involving 20 human patients suffering from chronic wounds—primarily due to diabetes or impaired blood circulation—the smart bandage demonstrated its ability to continuously sample wound fluid and detect important health markers.
The iCares bandage incorporates three specialized microfluidic modules that manage the flow of wound exudate. These components remove excess moisture, shuttle fresh fluid to a sensor array, and expel it from the bandage, ensuring that only the most recent and relevant samples are analyzed. This design prevents contamination by older fluids and enables highly accurate monitoring.
Equipped with a nanoengineered sensor array, the bandage can identify key biomarkers such as nitric oxide, which signals inflammation, and hydrogen peroxide, an indicator of infection. These indicators can be detected up to three days before physical symptoms emerge, giving caregivers a critical window for early intervention.
Further enhancing the system, the research team developed a machine-learning algorithm that analyzes the collected data to categorize wound types and predict healing times. The predictive accuracy of the algorithm matches the performance of expert clinicians, offering a valuable decision-making tool in wound management.
The physical structure of iCares is a flexible, biocompatible polymer strip that can be cost-effectively produced using 3D printing. Its single-use sensor component maintains hygiene, while a reusable circuit board processes data and transmits it wirelessly to smartphones or other devices.
Published in Science Translational Medicine, the study marks a significant step toward a future where smart bandages not only monitor but also actively support healing. The iCares device represents a fusion of biotechnology, microfluidics, and artificial intelligence aimed at transforming chronic wound care for patients and healthcare providers alike.
