In the United States, a team of researchers has created a cheap medical dressing that can help heal wounds at a surprising speed.
The technology developed by researchers at the University of Wisconsin-Madison is based on the production of electricity based on the movement of the human body and on its use to give electrical impulses through the bandage on the wound site.
Experiments have shown that the new bandage reduces healing time to only three days, compared to two weeks with traditional treatments.
"We were surprised by the fast healing rate of wounds," said Chudong Wang, a professor of materials science and engineering at the university. We expected the bandage to actually improve the recovery, but we did not expect it to be so high. .
Studies have shown decades ago that electricity can help heal skin wounds, but most devices used for this purpose are large and require complex connections, making it difficult to use everyday. .
