1. Low Power Current Sensing Node Powered by Harvested Stray Electric Field Energy
University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakultetenAbstract : In this thesis, the possibility of harvesting energy from a multicore power cableconnected to a power outlet is presented and evaluated. By surrounding a powercable with a conductive material connected to ground, it is shown that the dif-ference in potential between the power cable and the conductive material causesa capacitance which can charge a capacitor that in combination with an energymanagement circuit can be used to wirelessly transmit data with an interval de-pending on factors like the length of the surrounding material and the type ofcable it is placed around.
