Figure 9From: Design and Implementation of a Generic Energy-Harvesting Framework Applied to the Evaluation of a Large-Scale Electronic Shelf-Labeling Wireless Sensor NetworkEnergy-harvester emulation. Initially, there is no available energy. The application transmits one packet and listens three times. We see that the voltage drops during the radio activities and that it increases when more energy is harvested than is consumed (until the capacitor's maximum is reached).Back to article page
