Electrode-dressed bandage

Health Watch

An electrifying new bandage is looking to speed up the healing process.

Researchers at the University of Wisconsin have developed an electrode-dressed bandage to help the body heal itself. electrical currents are created when the body moves.

Xudong Wang, phd is an engineering professor at UW-Madison. He says, “We use that body generated electricity to help the wound recovery.”

Jun Li is an engineering student. He says, “So you just apply some pressure to the device and it could generate electricity.”

Those pulses of electricity stimulate cell regeneration and speed up the healing process at the wounded area. When the device was tested on rats, professor wang (wong) was shocked with the results.

Wang says, “Usually this wound will recover in two weeks. and our device helped the wounded recover in three days with minimal formation of scars.”

The idea to use electricity to heal wounds is not exactly new. there are large devices that treat patients with chronic wounds, but patients can only get them at the hospital. wang (wong) believes his technology can have big implications.

Wang adds, “We can make it a treatment become a daily normal treatment just like using a bandage from the grocery store. so people can handle that all by themselves.”

The researchers next step is to test the device on larger animals, like pigs and then human skin.

Right now the device can only treat acute, fresh wounds, but Wang is looking to work on hard-to-treat wounds, such as chronic wounds and burn wounds.
