Energy harvesting with current sensors to sustain embedded IoT platforms

Powering IoT devices is becoming a major issue due to the expected number of nodes to be installed in the next years. Powering those devices by harvesting energy from the environment can represent a solution for avoiding battery or AC/DC converters. In this paper, we present the study of an electrical energy harvesting power supply, using a current transformer sensor, as a feasible solution for powering low power embedded platform without batteries. The proposed system is not dependent on the load, and can be adapted to different scenarios and IoT applications.
