The photoactive device, which stimulates microcirculation and tissue regeneration, is currently being patented.
The research project is being carried out in collaboration with an industry partner and is scheduled for completion in 2026.
Iwona Nowak from the university’s Faculty of Material Technologies and Textile Design said there is a strong possibility the device could be available on the market within two years of securing patent protection.
'No other product like this available'
"There is currently no other product like this available," she said. "We hope that once it reaches the market, it will revolutionise diabetic foot care."
Nowak explained that the device was created using a textile-based material that is comfortable on the skin and embedded with a system of light-emitting diodes producing light waves at a wavelength of 630 nanometres.
The therapy involves applying a specific dose of light radiation – 4 joules per square centimetre – to encourage healing and boost blood flow.
"In diabetes, damage to blood vessels and nerves in the foot leads to oxygen-starved tissue," Nowak said. "The skin becomes dry and vulnerable to injury, leading to wounds that heal poorly, often becoming infected. In severe cases, this can result in the amputation of a toe, part or all of the foot, or even the leg."
She added that patients who undergo amputation due to complications from diabetes have a life expectancy of no more than three years, highlighting the importance of preventive treatments.
'Therapeutic sock'
Though the device has been nicknamed a "therapeutic sock" in the research project, it more closely resembles a soft strap fastened with Velcro and fitted with a diode system that emits light.
It has been specifically designed for ease of use by seniors, who are more frequently affected by diabetes and may require home-based treatment.
The team is now developing a companion mobile app that will work with built-in sensors to monitor skin moisture and temperature – two indicators that can reveal inflammation or poor hydration.
The app will also offer educational guidance to users, such as how to examine their feet and what types of physical activity are beneficial.
Diabetes is one of the most common chronic diseases in Poland, affecting an estimated 3 million people.
According to Nowak, around 25 percent of those living with the condition may not know they have it, as early stages often show no symptoms.
