Abstract [en]

Information theoretical tools are applied for the study of the sensitivity andselectivity enhancements of resistive fluctuation-enhanced sensors. Generalconsiderations are given for the upper limit of selectivity enhancement. The signal-to-noise ratio and information channel capacity of fluctuation-enhanced chemical sensors iscompared to that of classical sensors providing a single output. The considerations aredone at the generic level with a few concrete examples and include the estimation ofscaling relations between the sensor size, speed of measurements, sampling rate,measurement time, signal power and noise power.
