Abstract
A device for analyzing gas emitted from skin includes: an enclosure for collecting the gas emitted from skin, the enclosure having: an inlet through which a carrier gas is flown; and an outlet through which the carrier gas and the gas emitted from skin is flown into a vertical gas sensor, such that the vertical gas sensor has: a substrate; a collector layer; an emitter layer positively biased relative to the collector; a metal grid with a metal layer having openings, the metal grid located in between, but not in direct contact with, the collector and emitter; and an organic semiconductor (OSC) layer located in between the collector and emitter.
