A wearable wound monitoring device, featuring integrated sensors that promise to reduce infection risks by minimizing the need for frequent physical contact, has been developed by a team of researchers from RMIT University.

While traditional methods tend to require frequent removal of wound dressings for assessments, thereby delaying critical interventions, the new reusable device remotely monitors healing via a Bluetooth connection.

According to its developers, the device uses advanced integrated sensor technology — such as inflammation, pH and temperature sensors — to track important healing indicators. For instance, high temperatures tend to signal inflammation or infection, while pH level changes can reflect different stages of wound healing.

"We tested our wound monitoring device by simulating conditions it would encounter in wound management. We placed the device on a human arm to demonstrate that it conforms well to the curved surface. This was a test to show that this type of alternative monitoring technology is possible, and we are now ready to work with industry partners to develop it for clinical trials. Its components are biocompatible and fit seamlessly into existing manufacturing workflows and processes, potentially bringing the cost below $5 per unit when produced at scale," the researchers explained.

The study, "Multiplexed cutaneous wound monitor for point-of-care applications,” appears in the journal Advanced NanoBiomed Research.
