Abstract
A system for transdermal alcohol sensing to be worn near a skin surface of a user, including: an alcohol sensor; a microporous membrane; a housing coupled to the alcohol sensor and the membrane, defining a volume between the alcohol sensor and a first membrane side, and fluidly isolating the volume from a second membrane side opposing the first membrane side; an electronics subsystem electrically coupled to the alcohol sensor, operable to power and receive signals from the alcohol sensor; and a fastener operable to position the second membrane side proximal the skin surface.
Claims23
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.
