CHAPTER 10

MODELING, SIMULATION, AND INFORMATION PROCESSING FOR DEVELOPMENT OF A POLYMERIC ELECTRONIC NOSE SYSTEM

R. D. S. Yadava

1. INTRODUCTION

Development of electronic nose systems is bioinspired engineering that aims to impart odor-sensing capability to electronic machines analogous to the smell-sensing organ in humans, animals, and insects. In the biological domain, chemical signaling is very basic to evolution, survival, and social interactions of species. Every organism needs to sense its chemical environment. Animals and insects find food, detect predators and prey, mark territory, and select receptive mates via emission and detection of volatile chemicals. These molecules are mostly low-molecular-weight organic compounds. An odor is ...
