The zNose, A New Electronic Nose Technology for Homeland Security
Government sponsored Homeland Security initiatives have clearly defined the need for fast and accurate methods of detecting and identifying potential terrorist threats and there is increasing concern over key vulnerabilities particularly in maritime port security, airports, public buildings, and transportation facilities. The spectrum of conventional and non-conventional terrorist threats to homeland security continues to expand and existing fixed sensors are no longer adequate. Sensors that can quickly adapt and recognize conventional and non-conventional threats are needed.
