Back in 2015 I looked at an innovative new bandage from researchers at the University of California, Berkeley, which used electrical currents to detect tissue damage before it is visible to the human eye.
“We set out to create a type of bandage that could detect bedsores as they are forming, before the damage reaches the surface of the skin,” the developers said.
So, for instance, it could provide a regular monitoring service for a wound. The researchers documented their work in a paper that was published in Nature Communications.
This was then followed a year later by the work of a UK team, who have come up with a similar product. The bandage is capable of turning a different color when it detects the onset of infection, thus providing medics with an early warning of problems afoot.
The product, which was documented in paper published at the time, turns bright green when the gel like material within the dressing detects bacteria.
These are undoubtedly fascinating projects, but there appears little sign that they are coming to market any time soon. At least that’s the impression given by a Welsh team from Swansea University, who recently told the BBC that such bandages could be on trial within 12 months.
The bandages developed by the Welsh team utilize 5G technology to monitor what’s happening in the wound, whilst also tracking the activity levels of the wearer.
