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.
Claims20
A method for alcohol monitoring of a user, the method comprising:
- with an alcohol sensing device, receiving a set of samples into an analysis volume of an alcohol sensing device;
- processing the set of samples to determine a set of intoxication metrics;
- processing data collected at a temperature sensor of the alcohol sensing device, to determine a set of temperatures associated with the user and the set of samples;
- and
- determining a state of the alcohol sensing device based upon the set of temperatures.
