Gas sensing technologies -- status, trends, perspectives and novel applications
摘要：
气体传感器和电子鼻的强劲、持续进步提高了性能，并使越来越多的应用对现代社会产生了重大影响，例如环境监测、食品质量控制和呼吸分析诊断。在这里，我们回顾这一领域，特别关注已建立和新兴的方法，以及最近的突破，挑战和前景。特别是，我们专注于（1）气体传感器的不同架构中采用的转导原理，分析其优点和局限性;（2）传感层，包括最近的趋势，纳米结构，低维和复合材料;（3）在信号处理方法的进展，包括最近出现的人工神经网络。最后，我们总结了应用方面的最新成果和趋势。
英文摘要：
The strong, continuous progresses in gas sensors and electronic noses resulted in improved performance and enabled an increasing range of applications with large impact on modern societies, such as environmental monitoring, food quality control and diagnostics by breath analysis. Here we review this field with special attention to established and emerging approaches as well as the most recent breakthroughs, challenges and perspectives. In particular, we focus on (1) the transduction principles employed in different architectures of gas sensors, analysing their advantages and limitations; (2) the sensing layers including recent trends toward nanostructured, low-dimensional and composite materials; (3) advances in signal processing methodologies, including the recent advent of artificial neural networks. Finally, we conclude with a summary on the latest achievements and trends in terms of applications.
