DUAL HEAT PATH TEMPERATURE SENSOR

A temperature sensing system includes absolute temperature sensor(s) and/or thermopiles that form concentric geometries and are uniform in height. In some examples, the temperature sensing system can determine internal body temperature and/or ambient temperature based at least on a thermal gradient associated with the inner thermopile, a thermal gradient associated with the outer thermopile, a lateral temperature difference between the inner and the outer thermopiles, and an absolute temperature. In some examples, the temperature sensing system can determine the internal body temperature and/or ambient temperature using at least four absolute temperature sensors forming a concentric structure.
