Miniature, Ultrasensitive, Solid State Sensor for Atomic Oxygen

An extremely sensitive, low power, high durability solid state atomic oxygen sensor system with the potential for cost effective fabrication is proposed. It should lead to 1) improved understanding of the levels of atomic oxygen encountered during space missions; 2)quantification of the effects of atomic oxygen on a variety of materials in the space environment; 3) a warning mechanism for potential damage to structural components signaling the need for preventative maintenance and 4) possible weight savings as a result of a lessened need for intentional overdesign. The technology developed should result in the basis for a family of minature, solid state chemical sensors with ppb sensitivities.
