Traditional power management for battery powered devices does not meet the requirements of energy harvesting systems. Transducers that extract energy from the environment significantly differ from batteries in that their power output is limited. Besides, the energy source can be of variable nature and energy availability can be virtually infinite. Electronic systems that rely on energy harvesting...
Wireless sensors are normally powered by non- rechargeable batteries, but these must be replaced when depleted. Recent developments in energy harvesting technology allow sensors to be powered by environmental energy where it is present, but the wide range of situations where sensors are deployed means that it is desirable for the energy components of a sensor node (i.e. batteries, supercapacitors,...
