Radio frequency (RF) energy harvesting is founded on the ability of converting the energy carried by an electromagnetic wave through the air into electrical energy at the point of use. Though the physics behind RF energy harvesting is extremely simple and clear, transposing these principles into marketable technological solutions poses challenging issues. COPINE-IoT proposes the development of an original WPT technology in which the traditional wireless information gateways (IGs) are complemented with additional distributed and coordinated radiating elements, also referred to as remote power heads (RPHs). The RPHs shall be able of intercepting the flow of information from the wireless sensors to the IGs in order to enable the beamforming of the electromagnetic waves and sensors localization. The integration with the data communications system will permit the development of context-aware algorithms for energy management at the whole network scale. ULB-WCG is responsible for the design of the indoor localization of the ultra-low power sensors based on the estimation of the communication signals angle-of-arrivals at the RPHs equipped with multiple antennas.
