TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Breath respiratory species measurement during extravehicular activity (EVA) or intravehicular activity (IVA) is a demanding application for optical sensing techniques. Yet optical techniques offer many advantages including high-precision, fast response, and strong species selectivity. Accommodation within spacesuits demands that optical sensors meet stringent size, weight and power requirements. Vista Photonics proposes to develop rugged, compact, low-power optical sensor technology capable of selectively determining carbon dioxide at EVA-relevant concentrations. The enabling technology for meeting stringent NASA mission requirements is a new low power infrared optical source that provides the high-sensitivity of established optical absorption detection techniques.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The immediate targeted application for NASA is respiratory species monitoring during EVA and IVA. Phase II prototypes will be capable of selectively detecting carbon dioxide and water vapor. Other species can be included as required. The integrated sensors will be suitable for variable pressure EVA operation in diverse environments like the Moon, Mars and ISS. Unmanned planetary exploration missions in substantial atmospheres like Titan's are likewise contemplated. The emerging technology will also be suitable for use on both manned and unmanned terrestrial atmospheric research craft. Other applications include fire detection on aircraft and high-value installations, gas sensing in air revitalization and water recovery processes on spacecraft, and leak detection during spacecraft launch operations.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Phase III commercial applications abound for sensors whose performance and physical characteristics are suitable for spaceflight. Examples include contaminant monitoring in process gas streams in the chemical and microelectronics industries, medical diagnosis through detection of biogenic gases in human breath that correlate to specific pathologies, and environmental monitoring and regulatory compliance in agriculture, power production, and occupational safety. The fully-developed Phase II instruments shall offer a compelling and desirable blend of performance, affordability, compactness, simplicity and ease-of-use relative to present commercial product offerings in these applications.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
