Researchers from RMIT University have developed a wearable wound monitoring device with sensors that could reduce infection risks by minimising the need for frequent physical contact, healing remotely via a Bluetooth connection.
Conventional wound care often involves removing dressings to visually inspect healing, a process that can disrupt recovery and delay timely treatment. In contrast, this new device enables continuous monitoring through Bluetooth connectivity, allowing clinicians to assess wounds remotely without direct contact.
Developed as a reusable prototype, the sensor offers a more practical and affordable solution compared to single-use smart bandages and other similar technologies in development.
Chronic wounds affect millions worldwide, diminishing quality of life and placing a heavy burden on health systems. In Australia alone, an estimated 500,000 individuals live with chronic wounds, contributing to approximately $3 billion in annual healthcare costs.
Lead researcher Dr Peter Francis Mathew Elango explained that the device integrates miniaturised sensors capable of detecting inflammation, temperature, and pH levels—critical markers that reflect the healing status. Elevated temperature may indicate infection, while pH variations can help determine the wound’s progression through healing stages.
“To demonstrate the device’s practicality, we tested it under simulated wound care conditions,” said Dr Elango from RMIT’s School of Engineering. “We applied it to a human arm to show it adheres well to curved surfaces.”
“This experiment confirmed the potential for a non-invasive monitoring tool, and we’re now looking to collaborate with industry to move towards clinical trials.”
According to Dr Elango, the sensor components are skin-safe and compatible with current production techniques, suggesting that large-scale manufacturing could keep costs under $5 per unit.
