Abstract: The present invention relates to a novel method and apparatus for the amperometric determination of an analyte, and in particular, to an apparatus for amperometric analysis utilizing a novel disposable electroanalytical cell for the quantitative determination of biologically important compounds from body fluids.

Abstract: A method and apparatus for determining caloric expenditure of a subject. The apparatus includes a heat flow sensor having an overlay and/or conductive layer for measuring the evaporative heat loss, in addition to substantially total heat loss, for the subject. The sensor also includes a structure to enhance the migration of perspiration from edges or a bottom of the sensor onto an active region of the sensor. One sensor includes electrodes to effectuate electroendosmosis such that positively biased electrodes are formed at an edge or bottom of the sensor and a negatively biased electrode is formed at a center or top of the sensor. Through electroendosmosis the perspiration is migrated from the positively biased electrodes at the edge or bottom of the sensor to the negatively biased electrode in the center or top of the sensor. Another sensor places thermocouples at edges of a sensing portion to reduce a distance that the perspiration has to migrate.

Abstract: A device for signaling a wet condition in a diaper (12). The device includes a sensing means (10) for sensing wet conditions in the diaper (12) and signal means (15) connected to the sensing means (10) for producing a signal substantially concurrently with sensing the wet conditions in the diaper (12). The sensing means (10) are insulated from the wearer when the diaper (12) is dry and are activated by the diaper (12) once the diaper (12) becomes wet.
