1. A system for transdermal alcohol sensing to be worn near a skin surface of a user, the system comprising:

  • an alcohol sensor comprising a fuel cell, the fuel cell comprising a sensing electrode and a counter electrode;

    an inlet providing a path for a sample from the skin surface of the user to the alcohol sensor;

    a housing coupled to the alcohol sensor and comprising a barrier defining an aperture proximal the inlet, the aperture and the inlet cooperatively controlling flow of the sample to the alcohol sensor;

    an electronics subsystem electrically coupled to the alcohol sensor by way of the housing, the electronics subsystem operable to receive signals from the alcohol sensor and power the alcohol sensor; and

    a fastener coupled to the housing and operable to position the aperture proximal the skin surface.
