Highly Sensitive and Selective Receptor Materials for Membrane-type Surface Stress Sensor (MSS) and their Applications as an Artificial Olfaction

Abstract

Artificial olfaction is a technology that stays beyond our reach for decades because odors are highly complex mixture of gases, and the odor itself fluctuates in terms of time and space. Owing to the development of various innovative technologies in recent years, artificial olfaction is getting about to enter in range of the practical implementation. The receptor material has a key role to detect and/or discriminate the complex gases of versatile odors. In this chapter, we introduce the promising sensor system, “Membrane-type Surface stress Sensor (MSS),” especially about the developments of its receptor materials. In addition, we also introduce possible applications using advanced receptor materials.
