This paper briefly describes varied concepts developed and implemented to enhance the performance of gas-phase chemical microsensors. The developments are illustrated for chemiresistive microdevices, and involve efficient, array-based approaches to sensing materials selection and optimization, formulation of custom operating modes, and the use of bioinspired and life-extending methods. These devel...Show More

SENSORS, 2013 IEEE

Year: 2013 | Conference Paper |

We have studied the performance of a chemical microsensor array in a simulated Martian environment, which involved a carbon dioxide-rich background with low oxygen content (0.15 %) at low pressure and temperature to mimic the conditions at the Martian surface. Gas-phase target analytes (methane, ethane, hydrogen and sulfur dioxide) in complex ternary mixtures at concentrations of 200 nmol/mol and ...Show More

This study examines methods for decreasing the response time of chemiresistive, metal oxide microhotplate gas sensors. We describe a successful approach that employs an innovative pulsed-temperature operation methodology for increasing the speeds at which analytes may be recognized. By implementing the suggested strategy, we obtain, in a data-driven fashion, insights into the transduction mechanis...Show More

Applications for artificial olfaction typically require analytical performance in the context of diverse backgrounds. Therefore, to deal with practical challenges posed by chemical species recognition in the presence of pre-trained and untrained backgrounds, a desirable feature is the ability to rapidly detect fresh analyte introductions (foreground odor) and segment their contributions from the f...Show More

Improving the selectivity of a metal oxide nanowire gas sensor using a microhotplate/FET platform

Eric N. Dattoli;Kurt D. Benkstein

2011 International Semiconductor Device Research Symposium (ISDRS)

Year: 2011 | Conference Paper |

HTML

Summary form only given: Although metal oxide nanowires have been shown to be sensitive transducer materials when employed in gas sensors, e.g. such nanowire-based sensors have been shown to detect gaseous analytes at target concentrations of 1 μmol/mol and lower; they suffer from the deleterious issue of cross-sensitivity to a broad range of gases. To address this issue, a new sensor device struc...Show More

A major practical challenge for solid state microsensors is the detection of trace chemical species over time and in complex gas-phase backgrounds. We describe a MEMS-based, chemiresistive technology that has succeeded in such problems by combining oxide nanomaterials on microscale platforms, acquisition of dense temperature-dependent response data streams, and novel signal processing methods. Unl...Show More
