Researchers create a water-powered, disposable electric bandage that accelerates wound healing by 30% in animal testing.

Researchers from North Carolina State University and Columbia University have developed a water-powered, disposable electric bandage that can significantly accelerate chronic wound healing by up to 30% compared to traditional bandages. Known as water-powered, electronics-free dressings (WPEDs), the bandages use electrodes and a small, biocompatible battery to produce an electric field that promotes wound healing. The bandages are easy to use, cost-effective, and can be applied at home, increasing patient adherence and accessibility. In animal testing, chronic wounds treated with these electric bandages healed faster than those treated with conventional bandages.
