Contactless Sensors Detect Developing Pressure Ulcers, Trinity College Dublin Study

Medical-sensing technology could alert clinicians to the development of pressure ulcers in immobile patients before they form. The contactless system, developed by Irish researchers, focuses on detecting tissue blood flow — or perfusion — which when restricted can lead to ulcers. Currently there are methods to detect pressure at the interface between skin and supporting surfaces, but this only provides a proxy for perfusion.
