'STAR TREK DEVICE' COULD DETECT ILLNESS
Friday, 20 September, 2002
British scientists have developed a Star Trek style device which measures
vital health signs without the need for skin contact.
Researchers at Loughborough University believe their technology could one
day be used to measure blood flow, monitor the heart and assess how well
wounds and burns are healing.
The technique involves shining a light on a specific part of the body.
Potential health problems are identified by measuring how much light is
The technology has echoes of the devices used by doctors in the futuristic
The technology, developed by Professor Peter Smith and colleagues, is based
on a conventional technique, called photoplethysmography (PPG).
It measures how much light is absorbed by the body through pulse waves. The
size of these waves are determined by properties in the blood and how much
light is absorbed by the tissue.
PPG is already used to measure blood flow in parts of the body. However, the
difference with the Loughborough technology is that no skin contact is
The light can be emitted and measured from a small distance. The researchers
have developed a computer programme to take account of variations that might
occur as a result of body movement.
Vincent Crabtree, one of the researchers on the project, said further
studies were needed before the technology could have a more widespread use.
Speaking at the Photon02 conference in Cardiff, he said: "Future
applications for this technology could be extensive.
"However, the remote PPG signal quality has only been investigated over a
range of several centimetres so far."
