Electric bandage holds promise for treating chronic wounds

Researchers at North Carolina State University have developed an innovative electric bandage designed to enhance the healing of chronic wounds. This bandage utilizes an electric field to accelerate healing, demonstrating a 30% faster healing rate in animal tests compared to traditional bandages. Chronic wounds, such as diabetic ulcers, pose significant health risks, including amputation and death, and current treatments are often prohibitively expensive. The new bandage, known as a water-powered, electronics-free dressing (WPED), is lightweight, disposable, and can be activated simply by adding water. It features electrodes that conform to the wound's shape, allowing for effective electric field application. The study found that the WPEDs not only sped up wound closure but also promoted new blood vessel formation and reduced inflammation. The bandages are cost-effective, estimated to cost only a few dollars each, and can be used at home, increasing patient compliance with treatment. Future research will focus on optimizing the electric field's stability and duration, with the aim of advancing towards clinical trials. This work is part of a larger DARPA initiative aimed at developing personalized wound care solutions.
