This picture taken on November 9, 2015 shows Japan's University of Tokyo researcher Tomoyuki Yokota displaying an ultra-thin flexible thermal sensor on a plastic film at the laboratory of professor Takao Someya of the University of Tokyo. Someya and his team developed a thermal sensor that can be attached directly to the skin, potentially useful in monitoring the health of infants or even making sportswear more comfortable. The group said that the device, embedded in an ultra-thin film, can measure target temperatures between 25 and 50 degrees Celsius, a range that includes human body temperature. Photo: AFP
