MADISON, Wis. (WFRV) – After several years of exploration, researchers at UW‒Madison are close to finalizing a rapid self-healing bandage.

According to the UW-Madison School of Medicine and Public Health, the research that led to the creation of this bandage began in 2018 at the head of Xudong Wang, professor of materials science and engineering at UW-Madison. .

It was during this research that Wang and his colleagues discovered that the bandage they had created “significantly” accelerated wound healing in rats.

“When we tested it on injured human skin that we had grafted onto a mouse, the wound healed completely in seven days compared to the usual 30 days with a standard dressing,” said assistant professor Dr Angela Gibson. of surgery at the UW School. of Medicine and Public Health, and Burns and Acute Care Surgeon at UW HealthGibson.

With these promising results in hand, the researchers continued to perform further tests using the bandages and after about three years were able to make the necessary improvements to the product, bringing them one step closer to accomplishing their goal of develop an effective and fast self-healing bandage. .

“We have made improvements to the bandage between our original study and this one by incorporating the nanogenerator into the bandage itself and weaving the material to better mimic the way the skin stretches so it can pick up more energy. ‘energy of the subtle movements of the body’, Wang mentioned. “We are very excited about the results on human skin.”

According to UW-Madison researchers, bandages have been shown to heal a wound more than four times faster than a traditional dressing by using the body’s natural movement to generate an electric field.

The researchers explain that the bandage works by using a small generator, called a nanogenerator, to capture energy from natural movements like breathing and contractions. The nanogenerator converts this energy into mild electrical pulses which are sent to an electrode in the dressing, which then creates an electrical field around the wound, speeding up the healing process.

However, while the team is seeing positive results, their work is not done. Dr Gibson says next steps for the team include refining the design of the nanogenerator and bandage to further harness energy at various sites in the human body with the hope of moving into clinical trials in the next few years. .

Additionally, UW-Madison officials hope these futuristic bandages won’t cost too much to make because the bandages are easy to make and are made of “relatively” inexpensive materials.

“Given the simplicity of the device and its expected low cost, we really hope this technology will lead to significant improvements in the treatment of the millions of people who suffer injuries each year,” said Dr. Gibson.
