Abstract
This contribution deals with the use of chemical sensor arrays to develop microanalysis systems for gases which may serve as “electronic noses”. One particular sensor technology based on field effect devices is described in some detail. The principles of electronic noses are reveiwed. Some results obtained with noses incorporating field effect devices are presented. Different forms of integrated sensor arrays capable of generating detailed information about gas mixtures or odours are discussed. Micromachining can e.g. be used to create a temperature gradient along a sensor array. Furthermore, continuous sensing surfaces with a spatially resolved detection principle provide new possibilities regarding the microanalysis of gases.
