Sensors to prevent pain for amputees

Researchers at the University of Southampton have developed a new type of pressure sensor which they say could prevent damaging sores for many thousands of patients.

The technology has been funded by the Medical Research Council in a scheme to help scientists work with UK companies.

It is being tried out initially with amputees, who often suffer problems caused by rubbing against their artificial limbs.

Health Correspondent Adam Brimelow explains how the device works.
