Abstract: A sensor layer for determining temperature profiles on a skin surface. The sensor layer includes at least one ply, a contact layer with the skin surface, the contact layer being arranged on a top side of the at least one ply, a plurality of temperature sensors arranged at least one of in the at least one ply and on the top side of the at least one ply, and conductor tracks arranged at least one of in the at least one ply and on the top side of the at least one ply. The conductor tracks are electrically connected to the plurality of temperature sensors so that the sensor layer is formed to be flexible and so that a temperature difference on the skin surface can be determined via the contact layer.
