用于自供能传感器的环境能量源研究

Study on ambient energy sources for self-powering sensors

采集环境中的能量,实现传感器的自供电,可解决无线传感器携带电池能量有限的问题。自供能传感器能否从环境中获得充足的能量,与环境中的能量源密切相关。介绍了环境中常见能量源转换成电能的原理,并描述了这些能量源的特点、研究现状以及各自的优缺点,同时给出了不同能量源的适用范围,可作为自供能传感器采集环境能量时的参考。

The battery short-life issue of wireless sensors can be solved by self-powering technology, which is wireless sensors power themselves by converting ambient energy into electrical energy. Whether the self-powering sensors can obtain enough energy from the ambient depends on the kind of the ambient energy source. In this paper, the principles of the typical ambient energy sources converted to electdcal energy were introduced. The specialties, research status, relative merits and application ranges of these energy sources were described, which could be a reference to the self-powering sensors harvesting ambient energy.
