Electric plaster heals wounds quickly

London - A device that reveals if wounds are mending properly should speed up the healing process.

The WoundSense is a tiny sensor that sits inside a bandage or dressing and measures the levels of moisture in and around the wound. This gives vital clues on whether the environment inside the bandage is suitable for healing — moisture helps wounds close by encouraging the growth of new skin cells.

The modern plaster was invented in the US, in 1920 by Earle Dickson, who worked for Johnson & Johnson.

But if there’s too much moisture the skin cells struggle to regenerate. However, removing a bandage to check can also damage tissue and delay healing.

The device emits a very low electrical current and monitors the extent to which the current is impeded. This gives vital clues on the level of moisture as a current passes much more easily through fluid.

The device is about to be used in a trial treating injured military personnel at the Queen Elizabeth Hospital in Birmingham. - Daily Mail
