摘　　要：小尺寸、免维护、可移动的自供能系统尤其是自供能传感器具有非常广阔的应用前景。自供能系统本身可以从周围环境中收集能量并且转化为电能,为系统中各种功能器件的运行提供电源,因此自供能系统可以完全独立地实现特定的功能,而且能持续地工作。将收集环境中风能、太阳能、机械能等微小能量的自供能系统应用到气体传感器领域的研究十分有意义。目前,自供能气体传感器的实现有两种方式:一种是发展能收集环境中能量的设备去驱动传统的传感器,另外一种是自供能有源传感器,而第一种自供能气体传感器可以通过自身收集环境能量并对气体做出响应。该文对目前国内外基于收集风能、机械能以及太阳能的自供能气体传感器的设计方法、工作原理和特点进行了总结,为今后一体化集成式自供能气体传感器的研制提供参考。Small, maintenance-free and portable self-powered systems especially self-powered sensors have been widely used. Self-powered systems provide electric energy for various sensors by harvesting environmental energy. Therefore, it is very meaningful to develop self-powered gas sensors by harvesting clean energy, such as wind energy, mechanical energy, solar energy, and so on. The realization of self-powered sensors generally has two approaches the first approach is to develop environmental energy harvesting devices for driving the traditional sensors; the other is to develop self-powered sensors that can actively generate electrical signal by itself as a response to stimulation from the ambient environment. The structure design, operation principle and performance of several self-powered gas sensors that are driven by wind energy, mechanical energy, and solar energy are introduced systemically. This paper provide a reference for integrative self-powered gas sensors in the future.
