Review of the Multi-Input Single-Inductor Multi-Output Energy Harvesting Interface Applied in Wearable Electronics

Along with the industrialization and popularization of wearable electronics, an increasing number wireless sensor nodes (WSNs) are deployed. Nevertheless, conventional battery-based power supply system has no longer satisfied requirement large-scale WSNs in terms battery life, which emerges energy harvesting (EH) technique. In order to combine various sources drive multi-loads, multi-input single-inductor multi-output (MISIMO) EH interface applied electronics is spotlighted. this mini-review article, solutions for improving conversion efficiency (PCE) output quality MISIMO summarized. Furthermore, future trends also presented.
