Abstract:
1. A thermal sensor comprising an array of thermal resistors, said array comprising: a) a first polymer layer having an internal surface; b) a first plurality of thermal resistors patterned on said internal surface; each of said thermal resistors of said first plurality are provided in a first longitudinal direction, wherein said thermal resistors of said first plurality are not in direct physical contact with each other; c) an insulative polymer layer covering at least a portion of said internal surface and covering said first plurality of thermal resistors, said insulative polymer layer having a top face; d) a second plurality of thermal resistors patterned on said insulative polymer layer top face, wherein each of said thermal resistors of said second plurality are provided in a second longitudinal direction, wherein said second longitudinal direction is different than said first longitudinal direction, and wherein said thermal resistors of said second plurality are not in direct physical contact with each other; and e) a second polymer layer that covers said second plurality of thermal resistors; wherein each of the polymer layers are conformable, and wherein a spatial temperature variation in any of said first or second polymer layer generates a resistance variation in one or more of said thermal resistors.
