该论文提出了一种无电池、实时电流波形传感器，可从交流电源线进行无插头能量采集，并集成了发射器用于无线通信，解决了现有能源管理传感器体积大、无法贴在每个设备上且需要电池的问题。
are expected to be key to the achievement of an upgraded energy infrastructure, such as Smart Grid. While EMS may offer monitoring, reporting, and control of energy usage, these functions simply track intermittently the energy consumption and operational states of certain appliances and equipments. Further, since their sensing devices are not small, they cannot be attached to every appliance or piece of equipment. Some EMSs gather information, rather, at the power-distribution-board level or the multi-output-tap level. We report here a TX-integrated battery-free real-time current-waveform sensor. It is small enough to be attached to any piece of equipment for continuous power-consumption monitoring. Its key features are : 1) plugless energy harvesting (EH) from AC power lines, 2) real-time sensing and transmitting that use a half-cycle
