Abstract
An organic chemical sensor includes a dielectric core that comprises an elastomer and a high dielectric constant material. The elastomer absorbs an organic chemical to be sensed. An electrically conductive layer is secured to a first side of the dielectric core. A permeable conductive layer is secured to a second side of the dielectric core. The permeable conductive layer is electrically conductive and permeable to the organic chemical to be sensed. The absorption of the organic chemical to be sensed by the elastomeric layer causes a decrease in the capacitance between the electrically conductive layer and the permeable conductive layer.
