Abstract
The present invention relates to a device, system and method for determining the core body temperature of a subject. To enable continuous core body determination without having to place or direct a sensor at a precise position of the subject's body, the device comprises an image data input (31) for obtaining image data (11) of a subject's skin, a thermal sensor data input (32) for obtaining thermal sensor data (21) of the subject's skin, an image analysis unit (33) for deriving photoplethysmography, PPG, signals from the obtained image data and for detecting one or more skin areas (34) having the strongest PPG signals, and a temperature determination unit (35) for determining the core body temperature (36) of the subject from obtained thermal sensor data for the detected one or more skin areas.
