Wireless Power Transfer in Wirelessly Powered Sensor Networks: A Review of Recent Progress

Abstract: With the emergence of the Internet of Things (IoT), billions of wireless devices, including sensors and wearable devices, are evolving under the IoT technology. The limited battery life of the sensor nodes remains a crucial implementation challenge to enable such a revolution, primarily because traditional battery replacement requires enormous human effort. Wirelessly powered sensor networks (WPSNs), which would eliminate the need for regular battery replacement and improve the overall lifetime of sensor nodes… Show more

“…The locations of CSs can be fixed [ 45 ] or mobile [ 46 ]. Moreover, they may have multiple charging pads to serve multiple drones simultaneously via wireless power transfer [ 33 , 47 ]. Some designs consider collaboration between public transport, dedicated truck-based drone-enabled delivery, and CSs to execute drone-based delivery mission in remote areas [ 11 , 48 ].…”

“…Regarding the advantages and disadvantages of each EH solution, the most suitable to be used for wireless sensors embedded in an air cavity or a reinforced concrete cavity is the RF EH or WPT solution. Recent progress in the field of WPT for wirelessly powered sensor networks is presented [22]. It has proved its efficiency through some developments reported in [23,24].…”
