Scientists from the Institute of Textile Engineering at Lodz University of Technology have developed an innovative light-based therapy device designed to support home treatment of diabetic foot syndrome, a serious complication of diabetes.
The photoactive device, which stimulates microcirculation and tissue regeneration, is currently being patented.
As Dr. Eng. Iwona Nowak from the Faculty of Material Technologies and Textile Design at Lodz University of Technology points out, diabetes is one of the most common chronic diseases, affecting three million people in Poland. It is estimated around 25 percent of those living with the condition may not know they have it, as early stages often show no symptoms. Persistent hyperglycemia in diabetic patients leads to numerous complications, including kidney damage, peripheral vascular issues, sensory impairment, and diabetic foot syndrome.
“Diabetes damages blood vessels and nerves in the foot, leading to tissue hypoxia. The foot loses its ability to regulate skin hydration, resulting in excessive dryness and increased susceptibility to injuries. These injuries often develop into hard-to-heal wounds, which become infected and may ultimately necessitate amputations of toes, parts of the foot, or even the entire limb. Statistics indicate that a patient who undergoes leg amputation has a maximum life expectancy of three years. To prevent such complications, we have developed a light-activated device for home therapy of diabetic foot syndrome,” explained Dr. Nowak.
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.
Although referred to as a therapeutic sock in the project, the device resembles a fabric band fastened with a Velcro strap and equipped with a diode system that generates light. Since diabetes frequently affects elderly individuals and the device is intended for self-administered therapy, it has been designed for ease of use. Dr. Nowak also emphasized its pleasant texture.
“We are now preparing another project proposal, as an application is being developed for the device. In addition to its therapeutic function, the device includes multiple sensors to measure humidity—helping assess whether the foot’s moisture levels are improving—and temperature, which can indicate inflammatory processes. All data will be integrated into the application, which we aim to enhance further with additional features, such as guiding patients on foot examination techniques and recommended physical activities,” she added.
The research project at Lodz University of Technology is being carried out in collaboration with an industry partner and is scheduled for completion in 2026. According to Dr. Nowak, there is a high probability that the device will be available in stores within two years of obtaining legal protection.
“There is currently no such device on the market, so we hope that its introduction will revolutionize the treatment of diabetic foot syndrome,” the expert emphasized.
