Smart Environmental Monitoring by Low-Power / Self-Powered Gas Sensors and Artificial Intelligence

【Abstract】

With the advent of the 4th industrial revolution, there has been a significant rise in the use of Internet of Things (IoT) and advanced sensors in several sectors, including but not limited to smart factories, healthcare, environment, and entertainment. However, the deployment of an increasing number of sensors in IoT systems has made it crucially important but challenging to reduce their form factors and power consumption. Consequently, there is a growing need for sensors that are miniaturized, low-power, or self-powered. In particular, when it comes to environmental IoT, it is essential to decrease power consumption in gas sensors while simultaneously enhancing sensing performance factors, such as sensitivity, selectivity, and response speed. In this talk, we present some recent advancements in the development of environmental sensors that are miniaturized, low-power or self-powered. These sensors utilize functional nanomaterials, microfabricated sensor structures, and photo-activated sensing mechanisms, which were developed by our research group at KAIST. Additionally, we describe the implementation of deep learning-based signal processing techniques for ultra-low power environmental sensors. The following topics are covered in depth: (a) Low-power semiconductor metal oxide (SMO) based chemoresistive gas sensor array using localized hydrothermal synthesis, (b) Ultra-low-power SMO gas sensors monolithically integrated on a micro LED platform, (c) Self-powered gas sensors using chemo-optically modulating sensing films and photovoltaic cells, (d) Machine learning of gas sensor array for high performance electronic nose (e-nose) systems.

随着第四次工业革命的到来，物联网（IoT）和先进传感器在多个领域的使用显著增加，包括但不限于智能工厂、医疗保健、环境和娱乐。然而，在物联网系统中部署越来越多的传感器，使得减小它们的尺寸和功耗变得至关重要但又具有挑战性。因此，对小型化、低功耗或自供能传感器的需求日益增长。特别是在环境物联网领域，减少气体传感器的功耗，同时提高灵敏度、选择性和响应速度等传感性能因素至关重要。在本次演讲中，我们介绍了在开发小型化、低功耗或自供能环境传感器方面的一些最新进展。这些传感器利用了我们研究小组在KAIST开发的功能性纳米材料、微加工传感器结构和光激活传感机制。此外，我们还描述了为超低功耗环境传感器实现基于深度学习的信号处理技术。以下是深入讨论的主题：1.使用局部水热合成的低功耗半导体金属氧化物（SMO）基础化学电阻气体传感器阵列，2.单片集成在微LED平台上的超低功耗SMO气体传感器，3.使用化学光调制传感膜和光伏电池的自供能气体传感器，4.用于高性能电子鼻（e-nose）系统的气体传感器阵列的机器学习。
