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 is based on the generation of electricity based on the movements of the human body. It is used to transmit electrical impulses through the bandage to the position of the wound.
The trials showed that the new dressings reduced wound healing time to only three days, compared to two weeks if traditional treatment was used.
"We were surprised by the fast cure rate," said Chudong Wang, a professor of materials science and engineering at the University of Wisconsin Madison. We expected the dressing to actually improve recovery, but we are not expecting the recovery to be at this rate. "
According to Wang, the new technology is as simple as the use of traditional bandages.
He explained that the new dressings contain electrodes connected to micro-generation units installed around the patient's chest by medical tape. Electricity is generated according to the movement of the chest cavity during breathing and is used to direct small impulses to the wound position.
"The nature of these impulses is similar to how the body uses an internal electric field," Wang said. "This technique does not harm the healthy limbs of the body, unlike other medical devices that use a strong electrical current.
