Abstract

This experimental study investigates the duty-cycle passive times modifications for a low power wireless sensing system (WSS) designed for energy harvesting technology when its input power level and energy storage size are varying. The different low power WSSs presented in the literature feature specific designs aimed at solving particular problems, and due to their specificity their performance indicators are not directly comparable. As a result of this incompatibility, one cannot identify a correlation between the input power, energy storage element size, passive and active time variations to evaluate the potential usability of the system for static or dynamic testing. The present work covers this result comparison gap induced by the incompatibility factor, providing the experimental data obtained as a result of input power level and energy storage size variation for the same low power WSS, thus generating a
reference point for the advanced designer and also for the inexperienced user. The experimental results illustrate that, by varying the storage capacity of a low power WSS, its input power range can be enlarged by up to 20 times.
