SILICON MICROELECTRODE ARRAYS FOR IN SITU ENVIRONMENTAL MONITORING

WEI, XINGTAO

Abstract Details

2005, MS, University of Cincinnati, Engineering : Electrical Engineering.
Silicon microelectrode arrays for in situ environmental monitoring have been successfully developed in this work. Meniscus etching was used to sharpen these cantilevered probes. Microelectrodes with solid tips were fabricated for oxidation-reduction potential (ORP) measurements. Microelectrodes with recessed tips were fabricated for future developments of ion selective electrodes. Both microelectrode types were fully characterized with standard and reference solutions as recommended by the American Society for Testing and Materials (ASTM). The silicon microelectrodes have substantially smaller sensing areas (µm vs. cm) than their current commercial counterparts and exhibit significantly faster response times (milliseconds vs. minutes). Further, the sensors are robust due to redundant array configuration and the material strength of silicon. In the long term, we envision the use of these new sensors for field-based in situ monitoring in ground water quality and bioremediation applications.
