展望未来几十年的世界技术趋势，自供电传感网络是全球工业技术和经济驱动力的关键领域。自2006年以来，Zhong Lin Wang的团队提出了一种新的纳米发电机（NG）概念，包括压电纳米发电机和摩擦电纳米发电机，可以将机械触发转换为电力输出。考虑到运动无处不在地存在于周围环境中，并且对于每天使用的任何最常见的材料，NG可以固有地用作我们日常日益增长的需求的能源或作为自供电环境传感器之一。在这方面，通过耦合的压电或摩擦电性能与半导体气敏特性，一个新的研究领域的自供电气敏已被提出。最近的工作已经显示出实现基于NG的自供电气体传感器的有前途的概念，该气体传感器能够检测气体环境而不需要外部电源来激活气体传感器或主动地生成读出信号。与传统的传感器相比，这些自供电的气体传感器保持近似的性能。同时，这些传感器大大降低了功耗，还减少了集成所需的空间，非常适合可穿戴设备。本文简要介绍了天然气自供电气敏系统的建立、基本原理、最新进展和应用前景。展望了该领域的发展趋势，并介绍了其基本结构。
Looking toward world technology trends over the next few decades, self-powered sensing networks are a key field of technological and economic driver for global industries. Since 2006, Zhong Lin Wang’s group has proposed a novel concept of nanogenerators (NGs), including piezoelectric nanogenerator and triboelectric nanogenerator, which could convert a mechanical trigger into an electric output. Considering motion ubiquitously exists in the surrounding environment and for any most common materials used every day, NGs could be inherently served as an energy source for our daily increasing requirements or as one of self-powered environmental sensors. In this regard, by coupling the piezoelectric or triboelectric properties with semiconducting gas sensing characterization, a new research field of self-powered gas sensing has been proposed. Recent works have shown promising concept to realize NG-based self-powered gas sensors that are capable of detecting gas environment without the need of external power sources to activate the gas sensors or to actively generate a readout signal. Compared with conventional sensors, these self-powered gas sensors keep the approximate performance. Meanwhile, these sensors drastically reduce power consumption and additionally reduce the required space for integration, which are significantly suitable for the wearable devices. This paper gives a brief summary about the establishment and latest progress in the fundamental principle, updated progress and potential applications of NG-based self-powered gas sensing system. The development trend in this field is envisaged, and the basic configurations are also introduced.
