Compact MOEMS-based gas-sampling sensors for analysis of battery offgassing Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-056 Topic Title: Compact MOEMS-based gas-sampling sensors for analysis of battery offgassing Proposal No.: N101-056-0197 Firm: EPIR Technologies Inc 590 Territorial Drive, Suite B Bolingbrook, Illinois 60440-3542 Contact: Silviu Velicu Phone: (630) 771-0203 Web Site: www.epir.com Abstract: In order to satisfy the Navy's needs for the detection and identification of volatile organic compounds and other gases relevant to the compromise of lithium-ion batteries, we propose a compact, low-cost sensor based on the integration of HgCdTe emitter and photodiode detection technologies with micro-opto-electromechanical systems (MOEMS) technology. The size/weight/power characteristics of the proposed sensor are significantly superior to current Fourier transform-based optical sensor characteristics. The sensor is operated in a stand-off mode and has longer lifetimes than those of conventional solid state sensors based on chemo-sensitive layers. MOEMS technology will be used to tune the sensor wavelength, allowing for multiple agent detection. We will perform optical, electronic and systems studies and develop pattern recognition algorithms for quantitative spectral decomposition and compound identification. We will build a characterization set-up to assess the sensitivity, selectivity, false positive rates and probability of detection. These figures of merit will be compared with those obtained in standard Fourier transform setups. Benefits: New and emerging applications require the detection of narrow spectral lines in the infrared spectrum in order to allow clear material/object detection, chemical analysis, and accurate temperature measurements. The high performance spectrally sensitive optical sensors to be produced in the current program will have many military and commercial applications, including night vision and poor weather imaging for military operations and aircraft landing, ship navigation and search and rescue; target identification; surveillance; fire rescue in smoke-filled environments; industrial applications such as process control, large area temperature monitoring and preventive maintenance; environmental monitoring for pipe leaks, hazardous material spills, automobile exhaust emissions, and the status of high-power electrical systems; and non-invasive medical measurements of temperature for detecting tumors and measuring blood flow.
