1. A detection system for detecting at least ethanol in human sweat, the detection system comprising:
at least one sensor comprising an electrochemical gas sensor, wherein the at least one sensor is configured for detecting ethanol;
a measuring chamber with a waterproof, gas-permeable diffusion membrane, wherein the measuring chamber and the waterproof, gas-permeable diffusion membrane are configured such that substances excreted by the user via the user's skin are fed through the waterproof, gas-permeable diffusion membrane to the at least one sensor, at least a portion of the waterproof, gas-permeable diffusion membrane being located directly adjacent to the at least one sensor;
a diaphragm located at a spaced location from the waterproof, gas-permeable diffusion member, the waterproof, gas-permeable diffusion membrane and the diaphragm defining at least a portion of the measuring chamber; and
at least one seal configured to be brought into direct contact with the skin of a user and to protect at least the measuring chamber from environmental effects.
