Energy-Harvesting Platforms

Energy Harvesting PlatformsMany electronic devices, such as wireless sensor grids or implantable devices, operate in conditions where replacing or recharging batteries is unfeasible/uneconomical, and increasing the number of batteries to sustain the device for its intended operation time is either cost or size prohibitive. For such devices, harvesting energy from the ambient is necessary for extending their running time.




This research focuses on developing highly efficient, multi-input multi-output power conversion platforms with independent MPPT per input and regulated battery charging that can be employed in a wide variety of use scenarios.
