Abstract
A device for non-invasive measurement of the internal temperature of a physical body or thermal resistivity, the body comprising a thermally conductive medium between an internal region with a substantially constant internal temperature and an external surface with a surface temperature. The device comprises: a patch comprising one or more contact components for attachment to the external surface and an insulating cover for substantially thermally insulating the contact component from ambient thermal conditions; a reader for acquiring one or more thermal magnitudes on the patch; a processing unit for processing the thermal magnitudes to derive the internal temperature of the internal region or the thermal resistivity of the conductive medium.
