Researchers from North Carolina State University and Columbia Engineering have developed an innovative bandage that uses an electric field to promote faster healing of chronic wounds.
In a study published in Science Advances, the water-powered bandage demonstrated a 30 percent faster healing rate in animal tests compared to conventional methods.
Rajaram Kaveti, a postdoctoral researcher at North Carolina State University, and Assistant Professor Amay J. Bandodkar co-developed this promising technology. The bandage’s design allows for affordable and accessible treatment, enabling patients to use it at home.
Kaveti, who earned his doctorate from North Carolina State University and previously studied at Kongju National University, highlighted the bandage’s ability to provide the necessary electric stimulation to promote faster recovery. “Our goal was to create a bandage that accelerates healing and is accessible to patients outside of clinical settings,” he said.
Bandodkar emphasized the practicality of the bandage, which activates with a drop of water and allows patients to continue daily activities without visiting a clinic. “We wanted to develop a far less expensive technology that patients can easily use at home,” Bandodkar noted.
The study, titled "Water-powered, electronics-free dressings that electrically stimulate wounds for rapid wound closure," received support from the Defense Advanced Research Projects Agency and the National Science Foundation. Collaborators included experts from Columbia Engineering and Beth Israel Deaconess Medical Center.
