The project will develop a dual solar and electromagnetic energy harvester (EH) capable of simultaneously harvesting the available energy from light and microwave radiation at indoor application scenarios.
A highly efficient multiple technology harvester will be designed maximizing the combined DC output power from two energy sources available at indoor settings, light and 2.4 GHz ISM band microwave energy available from sources such as Wi-Fi routers and devices, Bluetooth devices, and microwave ovens.
A low profile, compact harvester circuit will be developed using flexible amorphous silicon solar cells and exploring flexible substrate materials for the antennas and electronics such as polyethylene terephthalate (PET) and paper and additive fabrication technologies (inkjet printing).
A cost effective solution will be developed based on low cost materials and off-the-shelf components, and a wireless sensor powered by the harvester will be demonstrated. The circuit will efficiently integrate a solar cell, antenna, super-capacitor and wireless communication and sensing in small form and additive manufacturing (3D printing) will be used to design low profile housing. The immediate benefit from this work is towards low profile, low complexity circuit architectures which can provide a dual technology and highly efficient harvester. The direct application of the proposed platform is that of an indoor battery-less, energy autonomous wireless sensor. The results of this work will provide a foundation, an enabling technology to explore ambient energy harvesting for ‘zero-power’ wireless sensors, implementing the notion of Internet-of-Things (IoT).
