People with artificial limbs are being offered hope for a more comfortable life thanks to research at the University of Southampton.
Scientists have created a sensor which not only spots when the prosthetic is starting to cause problems but it also lets the wearer know via an App on their smartphone.
They say it is the first of its kind in the world.
This new development is naturally of special interest to Royal Marine amputee, Cassidy Little.
The Strictly Come Dancing star gave his reaction to what the scientists at Southampton have come up with.
