Abstract
Using infrared sensors developed from those used in satellites for observing stars, the thermometer can take a reading in just two seconds. Its makers, Diatek of San Diego, claim it is accurate to within 0.1°C. A report in New Scientist says the thermometer measures temperature without coming into contact with the car or any mucous membranes so reducing the risk of infection: a particular risk with babies and seriously ill patients. A probe, covered with a disposable sheath, is placed at the opening of the ear canal. A microprocessor measures the heat picked up by the sensors and converts it into body temperature, which is then shown on a liquid crystal display.
