| 摘要 |
The invention relates to a chemical sensor, sensing system and sensing method which provides for a multi-sensor, cross-reactive, sensor array having a rapid response time, dynamic modulation of sampling parameters, and real-time feedback control of sampling and detection conditions. The device and method provide for smart detection and discrimination of analytes in fluids through intelligent sampling, detection, and control algorithms. The invention further provides for a sensor array having discrete sensor elements dispersed on fluid-permeable, high surface area, porous, textured substrates. The innovative device and method exhibit high sensitivity, discrimination and detection capability for target analytes at ppb and sub ppm concentrations.
