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.

用于在不断变化的环境中检测的人工嗅觉信号调制

动物已经进化为通过包括嗅探在内的调制行为以及包括记忆和神经调节在内的复杂神经处理在复杂环境中进行感知。在这里，我们探索了化学多样性传感器阵列的热调制，其中响应模式基于气味剂在阵列中的分配。差异响应模式包含有关用于识别的气味剂的化学性质的信息。通过从传统上在现场使用的明确定义的浓度调制过渡到热调制，可以在复杂环境中捕获诊断模式和强度信息。这种性能通过基于炭黑的、化学性质不同的传感器阵列得到证明，
