为了充分利用自然界的各种能源为微型传感器节点供电，设计了一种超低压启动，双电容蓄能，两级变压的微弱能源采集电路，并进行了温差发电的实例分析。结果表明，该电路能够在低温差条件下为蓄能电路积累能量，实现了低温差环境下的微弱能量采集，并能够根据无线传感器节点的间歇性工作的特点，快速做好供电准备。

In order to make full use of the energy of nature for the micro sensor node power supply,a weak energy harvesting circuit is designed with ultra-low voltage,double capacitor and two DC-DC converters. The analysis results about thermal power generation show that the circuit could accumulate energy under the condition of low temperature difference,and quickly prepare to power supply according to the charac-teristics of the wireless sensor node of intermittent work.
