Description

Microsensor systems are constructed from modular components that include device platforms, sensing materials, control and signal-acquisition circuitry, and signal-processing/pattern-recognition algorithms. The sensors must be tailored for the particular nature of a given chemical or biochemical measurement problem by optimizing and properly integrating the various components. Measurement needs now being defined by the energy, homeland security, environmental, and health-care sectors are challenging sensor-science researchers to develop technology that can operate at unprecedented levels of sensitivity and discrimination, and in highly varied backgrounds (ranging from corrosive industrial exhaust, to planetary atmospheres, to cell cultures and human breath). This project focuses on the development of advanced sensing components-individually or within sensor systems-that can help to push performance to new levels, thereby impacting critical new application areas. We are particularly interested in examining the benefits that can be attained by applying novel concepts including, but not limited to, incorporating and/or assembling nanostructured building blocks and functionalized surfaces, constructing high-dimensionality devices, utilizing multi-element arrays with modulation techniques, and employing bio-inspired signal-processing protocols. Additionally, reliable performance is critical and we are interested in developing (1) methods to prepare highly reproducible MEMS and NEMS device platforms, sensing materials, biomolecular interfaces and sensor material-electrode contacts; and (2) methods to reduce/eliminate drift and to provide self-calibration routines.
