“…47 As a result, there is considerable interest in providing similar capabilities to robots 48 and UAVs 49 to enable these sorts of tasks in autonomous and stand-off monitoring systems. To explore the feasibility of using temporal modulated responses for plume tracking, a concentration profile (Figure 4a) was simulated to represent temporal variations that could be experienced by an organism 50 or an autonomous tracking system 51 maneuvering up a concentration gradient to a source, periodically exiting the plume and returning based on a drop in concentration. 52 The sensor array was exposed to the temporal concentration profile for isopropanol (Figure 4b), and processed as described above, utilizing the principle component calibration from the training set.…”

Animals have evolved to sense in complex environments through both modulation behavior including sniffing as well as sophisticated neural processing including memory and neuromodulation. Here, we explore thermal modulation of chemically diverse sensor arrays, where response patterns are based on partitioning of odorants across the array. The differential response patterns contain information about the chemical nature of the odorant for identification. By transitioning away from well-defined concentration modulation, traditionally used in the field, to thermal modulation, it is possible to capture both diagnostic patterns as well as intensity information in complex environments. This performance is demonstrated with carbon-black based, chemically diverse sensor arrays, that are thermally modulated with light at 25 mHz exposed to different analytes of varying concentrations.
