FLEXIBLE DEEP TISSUE TEMPERATURE MEASUREMENT DEVICES

The present invention relates to a temperature device, comprising a flexible substrate having first and second sides; the flexible substrate including a circular center section, a tab contiguous with the center section and extending from the center section in a first radial direction, and a tail contiguous with the center section and extending from the center section in a second radial direction; a first thermal sensor disposed on the first side, substantially at the center of the center section; a heater trace disposed on the first side, in the center section, around the first thermal sensor; a second thermal sensor disposed on the first side, in the tail; a plurality of electrical pads disposed on the first side, in the tab; a plurality of traces disposed on the first side and connecting the first and second thermal sensors and the heater trace with the plurality of electrical pads; the center section and the tail folded together to position the first and second thermal sensors in a spaced-apart relationship; and, a layer of flexible insulation disposed between the folded-together center section and tail.
