  • Publication number: 20150297146
    Abstract: Embodiments of the invention provide systems and methods for remote sensing and/or monitoring utilizing a sensing device, such as may be implemented in a patch that can be placed on or affixed to a subject, where the sensing device includes multiple sensors. For example, one embodiment of the present invention includes a wireless human temperature skin patch providing accurate measurement of human temperature from a sensing device applied to the skin and even in the presence of differing ambient temperature. In such an embodiment, the patch can include, for example, a flexible, breathable bandage or adhesive strip or pad to affix the sensing device to a patient. The sensing device can include multiple sensors such as two or more temperature sensors that can be used to accurately determine the patient's core body temperature from the measured temperature at the skin.
