Abstract
We have developed a new portable electronic nose based on a SAW sensor array and its readout electronics. The SAW array is based on 2×2 non-continuously working oscillators for sensors coated with different polymer/mesoporous carbon composite materials. Signals of the SAW array can be obtained by a readout PCB and a microprocessor. Experiments indicate good results for this portable system to perform gas detection and recogntion applications. © 2009 American Institute of Physics.
