Simulation and Design of Micro Inductor for Electromagnetic Energy Scavenging at Low Ac Frequency in Wireless Sensor Network

چکیده
This paper presents a prototype of wireless sensor node for power management of information and communication technology (ICT) devices at low AC frequency. Electromagnetic simulation and experiments were carried out for discussing the miniaturization of the sensor node. The good fit between the simulation and experimental results on the induction voltage of a commercial meso-scale inductor, suggested that energy scavenging is possible at low AC frequency. However, the measured induction voltage deviated much from the simulated ones with the reducing of inductor size. A careful selection of core material and design is required for realizing micro inductor-based current sensing and power generation by MEMS technology.
