Patent ID: 8325048

Claim:
A device for non-invasive monitoring thermal stress of a user comprising: a. a monitoring unit comprising 1) a first substrate comprising a first side and an opposite second side; and 2) at least two temperature sensors, wherein at least one temperature sensor is located of the first side of the first substrate and at least one temperature sensor is located on the second side of the first substrate, each temperature sensor is directly or indirectly connected to said first substrate; b. a cover comprising a first side and an opposite second side, where the first side of said cover has a defined surface area, said defined surface area has a first area and a second area, said cover being adapted to receive the monitoring unit in the first area of said defined area: and c. a thermally conductive member contacting the temperature sensor on the second side of the first substrate, the thermally conductive member extending through the second side of the cover.
