Abstract

A detection system (100) detects at least ethanol in human sweat. The detection system (100) includes at least one sensor (105) that is an electrochemical gas sensor. The at least one sensor (105) is configured at least for the detection of ethanol. The detection system (100) further includes a measuring chamber (107), in which substances excreted by the user via the user's skin can be fed via a waterproof, gas-permeable diffusion membrane to the at least one sensor (105). The detection system (100) further includes at least one seal (127), which is configured to be brought into direct contact with the skin of a user and to protect at least the measuring chamber (107) from environmental effects.
