The reusable prototype incorporates flexible sensors capable of monitoring inflammation, pH and temperature levels at the wound site. It uses a Bluetooth connection to transmit data remotely, reducing the need for frequent dressing removal and physical contact with the wound.

Reducing Infection Risk Through Remote Monitoring
The device is being positioned as a lower-cost and more practical alternative to disposable smart bandages and other digital health products under development. It aims to address a widespread healthcare challenge, particularly for patients suffering from chronic wounds.

About 500,000 Australians are affected by chronic wounds, which collectively cost the national healthcare system around $3 billion each year. Globally, the problem affects millions of patients.

Lead inventor, Dr Peter Francis Mathew Elango, from RMIT’s School of Engineering, said the team focused on building a non-invasive, reusable system that integrates into existing care routines.

“We tested our wound monitoring device by simulating conditions it would encounter in wound management,” Elango said.

“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.”

Underlying Tech And Cost Focus
The platform uses high-resistivity silicon-based sensor technology to detect temperature and pH changes, both of which can signal inflammation, infection or various healing stages.

Elango said the design could be manufactured for less than $5 per unit at scale, with all components made from biocompatible materials compatible with existing manufacturing workflows.

The sensors can be placed on or next to a wound and remain in place under conventional dressings. Their flexibility makes them adaptable to different wound shapes and body areas.

Developed From Proven Research Stream
Professor Madhu Bhaskaran, who leads RMIT’s Functional Materials And Microsystems Research Group, said the core sensor platform used in the wound monitor had already demonstrated versatility in detecting biomarkers for other medical applications.

“The high-resistivity silicon-based sensor technology is our platform IP that has been proven to be efficient at multiple biomarker detection related to different ailments,” Bhaskaran said.

Her group has previously developed bedding sensors to monitor comfort and sleep quality in aged care settings. Elango has also worked on a wearable heart monitor, now progressing toward commercialisation through a partnership with Perth-based Lubdub Technologies.
