We present the design of a fluidic gas multi-sensors chamber to be integrated in a portable device for multi-modal detection and identification of gas. The multi-sensors chamber has 14 sensors; 4 fluorescent sensors, 2 Quartz crystal microbalances (QCM) and 8 surface-acoustic-wave sensors (SAW). The weight of the chamber is about 500 g with a 9 ml fluidic volume. We used the fluidic simulation to optimize the flow inside the chamber. The chamber design has been experimentally validated with gas test bench. This work, initially developed for civilian safety applications, can be extended to others applications such as environmental monitoring to detect and identify gas nature.
