Research of Technology of Environmental Electricity Generation of Radio Wave for WSN Application

为了解决WSN节点的供电问题,提出了一种采用环境无线电波为WSN节点供电的环境发电方案,详细介绍了无线电波环境发电系统的构成及RF-DC转换电路的组成与性能。理论分析和ADS仿真结果表明,在输入信号功率为0 dB.m的条件下,4级倍压整流电路能够获得约4.3 V的输出电压,初步验证了该方案的可行性。

In order to solve the problem of power supply of WSN node, the paper put forward a scheme of environmental electricity generation of using environmental radio wave to supply power for WSN node. It detailly introduced composition of environmental electricity generation system of radio wave and composition and performances of RF-DC converting circuit of the system. The results of theory analysis and ADS simulation indicated that 4-grade voltage-multiplier rectifier can get 4.3 V output voltage on condition that power of input signal is 0 dB.m, which verified feasibility of the scheme tentatively.
