The research on electronic tongue for environmental detection

This paper describes the research work of our electronic tongue for detection in environment. We introduce the principles and structures of several kinds of novel integrated ion sensors, including the integrated ion sensors based on surface optical potential technique and the integrated ion sensors array on chemical, optical principle, develope the microstructural ion sensors using fabrication techniques on silicon techniques, discuss the signal processing and pattern recognition algorithms and design a novel electronic tongue instrument for detection heavy metal ions in seawater. This paper gives some experiment results in environmental detection of electronic tongue.
