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

Abstract

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

SPICE modelling and analysis of hybrid energy harvester combiner topologies

“…In order to investigate if this SPICE framework can effectively simulate various combiner topologies that have been published, a comparison and analysis is detailed in Table 4. Certain articles ([5], [7], [23], [31], [33], [35], [37]) that deal with commercial off-the-shelf (COTS) ICs or systems, systems design, reviews, or studies have been left doi: 10.31593/ijeat.1217710 out from this comparison. Also, references [25] to [30] mainly focus on matching sources and power converters in terms of impedance, and don't emphasize the ways to combine energy, which is why they aren't part of Table 4.…”
