1. A temperature determination device, comprising:

  • a patch defining a first surface and a second surface opposite the first surface, wherein the first surface is removably attachable to skin of a subject at a first location of the subject'"'"'s skin;

    a first temperature sensor connected to the patch and configured to detect a temperature of the first surface;

    a second temperature sensor connected to the patch and configured to detect a temperature of the second surface; and

    at least one additional electronic sensing component connected to the patch and configured to determine a metric, other than temperature, indicative of a first amount of blood flow proximate the first location, wherein a controller in communication with the device is programmed to;

    receive a first signal from the at least one additional electronic sensing component indicative of the metric as determined by the at least one additional electronic sensing component while the patch is disposed at the first location,compare the metric to a threshold corresponding to the metric,determine, based at least partly on comparing the metric to the threshold, that the patch should be repositioned to a second location of the subject'"'"'s skin characterized by a second amount of blood flow less than the first amount, wherein determining that the patch should be repositioned includes;

    determining that the metric exceeds the threshold, andoperating an operator interface device to indicate that the patch should be repositioned,receive a second signal from the at least one additional electronic sensing component indicative of the metric as determined by the at least one additional electronic sensing component after the patch has been repositioned to the second location,determine, based at least partly on the second signal, that the metric as determined by the at least one additional electronic sensing component after the patch has been repositioned to the second location is less than or equal to the threshold, andcalculate, at least partly in response to determining that the metric as determined by the at least one additional electronic sensing component after the patch has been repositioned to the second location is less than or equal to the threshold, a core temperature of the subject based on the temperature of the first surface, the temperature of the second surface, and an estimated thermal resistance of the subject'"'"'s skin.
