Methods for Optimizing and Extending the Performance of Chemiresistive Gas Microsensors



Kurt D. Benkstein, Alexander (. Vergara Tinoco, Christopher B. Montgomery, Baranidharan Raman, Stephen Semancik


This paper briefly describes varied concepts developed and implemented to enhance the performance of gas-phase chemical microsensors. The developments are illustrated for chemiresistive (MEMS) 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 developments, which are essentially modular in nature, can enable required levels of sensitivity and speed while also introducing application-specific selectivity. Examples from diverse application areas are provided to demonstrate performance characteristics and extended operation capabilities.
