An electronic nose system for urban search and rescue operations
Abstract
In this thesis the successful testing of an electronic nose system is presented, as well as all the required research to achieve that goal. This electronic nose is intended to detect the presence of trapped humans in confined spaces and, also, air-related hazardous conditions in collapsed buildings during search and rescue operations in an urban environment. Initially, the field of interest for which this work provides a solution is presented. Existing methods, with and without gas sensors, are presented and the environment in which the electronic nose is intended to work in is investigated from a measurement and detection perspective. Various sensing technologies and their capabilities are presented. Also, the anticipated target gases/compounds which are indicators of human presence are listed and an estimation regarding the feasibility of detecting them is produced, given some specific constraints that must be met in order for the end result to be practically usable in real condition ...
