集成能量收集和未来无线模块
 
  使用无线模块开辟了新的方法来实现成本效益的传感器节点的应用,如物联网(物联网)。简单的模块,以及使用低功耗无线协议,允许能量采集子系统捕捉能量从环境中存储本地,如图1所示。这可以减少甚至消除需要更换电池,并允许开发人员实现传感器在许多更难以进入的地方。

  Figure 2 shows the different wireless technologies and their suitability for using energy harvesting as a source of power. Protocols such as EnOcean have been specifically developed for energy harvesting applications with simple low-power techniques and structures such as telegrams, while others, such as Z-Wave, ZigBee and Wireless HART, are low-power extensions of existing wireless or industrial protocols that can also be used.
