Accurate supercapacitor modeling for energy-harvesting wireless sensor nodes

, 2011
Supercapacitors are often used in energy-harvesting wireless sensor nodes (EH-WSNs) to store harvested energy. Until now, research into the use of supercapacitors in EH-WSNs has considered them to be ideal or over-simplified, with non-ideal behavior ...
