An overview of film-based microsensors and applications

PDF Version Also Available for Download.

Description

Many chemical analysis problems exist that encourage the development of small, low-cost, low power, chemical sensors in many of these applications, while speciation of the sample is unnecessary due to prior knowledge of the sample constituents, it is necessary to monitor, in near real-time, the concentration of a Particular species of interest, An example of this of problem would be the monitoring of a chemical process such as steam reforming of chemical waste or ground water monitoring where prior laboratory analysis has determined the constituents. In applications such as these, it is worthwhile to trade off the sensitivity and speciation ... continued below

Description

Many chemical analysis problems exist that encourage the development of small, low-cost, low power, chemical sensors in many of these applications, while speciation of the sample is unnecessary due to prior knowledge of the sample constituents, it is necessary to monitor, in near real-time, the concentration of a Particular species of interest, An example of this of problem would be the monitoring of a chemical process such as steam reforming of chemical waste or ground water monitoring where prior laboratory analysis has determined the constituents. In applications such as these, it is worthwhile to trade off the sensitivity and speciation that can be obtained by taking individual samples and analyzing them in a laboratory for the near real-time, low-cost measurements that can be achieved using a solid-state transducer. In this paper, several different types of sensor platforms and applications that require CSFs bonded to the platform will be discussed. Among these are surface acoustic wave (SAW) based sensors, optical fiber-based sensors, and Si-based sensors. Each will be described and applications will be discussed.
