Abstract

In this paper, we present a compact flexible electromagnetic energy harvester systems using a small loop resonator. They are designed and fabricated on a flexible substrate, and their performance are verified through measurement for both flat and curved configurations. The efficiency is investigated with respect to power density. It is observed that the proposed systems can achieve high conversion efficiency for low input power while at the same time occupying a compact footprint areas. In addition, the output DC power by harvester system using multi-resonator array is compered to a system with a single resonator. The measurement results demonstrate that an enhancement in the performance of up to 4 times are achieved.
