Wireless power transfer (WPT) has emerged as a promising technology for future communication systems, particularly in the context of the extensive connectivity of heterogeneous, ultra-low-power devices within the Internet of Things (IoT) and Internet of Everything (IoE). A significant challenge these systems face is ensuring the energy sustainability of these devices. Conventional solutions, such as frequent battery replacement or energy harvesting from natural sources, are often unreliable, costly, or infeasible in many cases. WPT addresses this issue by enabling devices to harvest energy from dedicated or ambient electromagnetic radiation sources, ensuring a continuous power supply. The integration of WPT technology into communication networks introduces a fundamental co-existence of information and energy flows. Specifically, within this framework, radio frequency signals are used to simultaneously transmit both information and energy, giving rise to a communication paradigm known as simultaneous wireless information and power transfer (SWIPT). SWIPT necessitates the efficient co-design of both information and power transfer to balance the dual demands of energy sustainability and data communication.

The primary goal of this Research Topic is to present cutting-edge advancements in WPT/SWIPT technology and emphasize its advantages from its integration in future wireless communication systems. The widespread adoption of IoT/IoE will lead to the large-scale deployment of low-power devices and an overwhelming volume of information exchange. This makes it increasingly impractical—if not impossible—to individually recharge or manage these devices on a regular basis. In this context, SWIPT offers a powerful solution by co-engineering information and energy signals. It ensures continuous, fully-controlled energy harvesting while simultaneously enabling communication connectivity. This eliminates the need for frequent battery replacements or wired recharging, preventing disruptions to critical services such as healthcare, finance, and public safety due to depleted batteries. As IoT/IoE transceivers continue to shrink in size and improve in energy efficiency, we foresee a future where radio waves not only serve as a primary energy source for powering devices but also seamlessly integrate information and energy transmission.
