 摘要：无线传感器网络(WSN,wireless sensor network)具有节点能量有限及电池更换困难等特点。无线传感器网络节点的功耗是影响整个网络寿命的关键。另外，低功耗技术也是影响传感器网络能否通过本质安全认证从而能在危险环境中得到应用的关键。从硬件及软件两个方面详细阐述了符合本质安全认证的低功耗嵌入式WSN节点的设计技术。 |

| Abstract：The nodes of wireless sensor networks (WSN) have the characteristics of limited power and difficulty to replace the battery.The power consumption of the WSN nodes has become the key factor of the whole network’s life.Otherwise,low power technology is the key factor of deciding if a WSN node could pass the intrinsic security (IS) certification and be used in the dangerous environment.The low power consumption WSN nodes designing technology from hardware and software is elaborated. |
