Abstract

A double temperature sensor is provided for determining the body temperature. The sensor includes at least a first temperature sensor element for measuring a near-surface temperature of the ambient air and a second temperature sensor element for measuring a temperature of the skin surface. The first and the second temperature sensor elements are arranged in a sensor block. A holding element surrounds the sensor block at least partially. An adhesive element fixes the holding element on the skin surface. A spring element acts on the sensor block and provides a spring force directed in the direction of the skin surface.
