A new revolution in the world of wounds … electronic dressing

In the United States, a team of researchers has created a new inexpensive medical dressing that can help heal wounds at a surprising rate. The technology developed by researchers at the University of Wisconsin in Madison, United States, to generate electricity based on the movements of the human body and to transmit electrical impulses through the bandage located on the site of the wound.

"We were surprised by the rapid healing rate of wounds," said Chudong Wang, professor of materials science and engineering at the University of Wisconsin Madison. "We were expecting the dressing to actually improve recovery, but we were not expecting such a quick recovery."

Scientific studies also confirmed decades ago that electricity can help heal skin wounds, but most devices are used to generate electricity for this purpose.

Wang explains that the new technology is as simple as the use of traditional bandages. "He explains that the new dressings contain electrodes connected to micro-generation units installed around the patient's chest with medical tape." The nature of these impulses is similar to the way the body uses an internal electric field "said Wang, adding that this technique did not cause any harm to the healthy limbs of the body, unlike other medical devices using an electric current.
