Wearable sensorfor real-time, continuous monitoring of vital signs


Research background

The Carelight technology has been developed in Loughborough University’s Photonics Engineering and Health Technology Research Group, which has many years of experience in optical detection technologies and particular expertise in healthcare applications, including both in vitro and in vivo detection systems.

The group has a particular interest in photoplethysmography (PPG), where body tissue is optically monitored and variation in blood volume or blood flow is measured to determine various physiological parameters. A novel opto physiological modelling approach has been developed that underpins the design and implementation of new sensors, addressing both imaging and contact PPG. Since 2005 almost 50 papers have been published that describe basic principles, technology developments and applications.

Our specialist partner - the National Centre for Sport and Exercise Medicine (NCSEM), co-located on the University campus - conducts a rigorous validation programme in its outstanding facilities.

Loughborough hosts the East Midlands hub of this Department of Health initiative to transform the delivery of Sport and Exercise Medicine within the UK.
