Optical gas sensors play an increasingly important role in many applications. Sensing techniques based on mid-infrared absorption spectroscopy offer excellent stability, selectivity and sensitivity, for numerous possibilities expected for sensors integrated into mobile and wearable devices. Here we review recent progress towards the miniaturization and integration of optical gas sensors, with a focus on low-cost and low-power consumption devices.
光学气体传感器在许多应用中发挥着越来越重要的作用。基于中红外吸收光谱的传感技术具有出色的稳定性、选择性和灵敏度，为集成到移动和可穿戴设备中的传感器带来了众多可能性。在此，我们回顾了光学气体传感器在小型化和集成方面的最新进展，重点关注低成本和低功耗设备。
