A multidisciplinary team led by the Korea Advanced Institute of Science and Technology (KAIST<\/a>) has developed a wireless, battery-free “smart patch” (dressing). The device monitors diabetic foot wounds in real-time and provides clinicians with information regarding early signs of deteriorating conditions.<\/p>\n

Foot ulcerations are considered a common and serious complication among patients with diabetes. When infection, impaired blood circulation, or inflammation progresses unnoticed, the process often culminates in tissue necrosis and amputation. Consequently, constant monitoring of the patient’s condition and early diagnosis play a decisive role. However, current approaches rely on frequent clinic visits, invasive procedures, and visual inspections. In the intervals between these check-ups, rapid deterioration of the wound status can often go undetected.<\/p>\n

How the Dressing Works<\/strong><\/h5>\n

The device integrates two components into a single wound dressing:<\/p>\n

Color-Changing Functional Nanofiber Dressing: Manufactured using a special method called electrospinning, this dressing contains colorimetric indicators. These indicators change color in response to rising glucose levels and shifts in acidity (pH). These two markers often indicate the presence of infection or the worsening of an ulcer.<\/p>\n

Embedded Miniature Optoelectronic Sensor System: A light-emitting diode (LED) illuminates the surface of the wound, while a photodiode measures the reflected light. The sensor then converts color changes into stable electronic signals. Notably, unlike a standard smartphone camera, this internal sensor is not affected by external ambient room lighting.<\/p>\n

Autonomous Operation with Smartphone Support<\/strong><\/h5>\n

The primary value of this technology lies in its wireless and battery-free construction. A flexible microcircuit integrated into the device operates based on NFC (Near-Field Communication) technology: when a smartphone is brought close, the phone wirelessly supplies power to the patch and instantaneously records the necessary data. As a result, wound status monitoring is carried out via a specialized mobile application. This approach simplifies the treatment process for both patients and medical personnel without the need for additional hardware, wires, or frequent dressing changes.<\/p>\n

Limitations and Next Steps<\/strong><\/h5>\n

The new technology has shown very promising results during the initial preclinical stage. Nevertheless, large-scale clinical trials are essential to fully evaluate the patch’s performance in daily practice, its correct usage by patients, and its actual impact on amputation rates.<\/p>\n

In terms of long-term wearability, future work must test the dressing’s durability in everyday environments. Researchers must confirm the device’s mechanical stability, patient comfort, and the continued accuracy of its readings over several days or weeks of practical use.<\/p>\n
