In recent years, the simultaneous integration of Wireless Power Transfer (WPT) and Information Transfer (IT) has garnered significant attention as a transformative approach to wireless communication systems. This integration aims to combine the capabilities of efficient energy transmission with seamless data communication, promising enhanced functionality and flexibility across various applications. This paper reviews the latest advancements, trends, challenges, and future directions in the convergence of WPT and IT technologies. The integration of WPT and IT technologies encompasses several innovative approaches. Magnetic resonance coupling and resonant inductive coupling are pivotal techniques that enable efficient energy transfer between transmitter and receiver coils, utilizing resonant frequencies to minimize energy loss and optimize transmission efficiency over short to moderate distances. These techniques are complemented by non-resonant methods using microwave and Radio Frequency (RF) technologies, which extend the operational range and power capacity of WPT systems, making them suitable for diverse applications in consumer electronics, healthcare, automotive, and industrial sectors.

Advanced beamforming technologies further enhance the performance of integrated WPT-IT systems by directing electromagnetic waves towards specific receivers, thereby reducing interference and optimizing power delivery efficiency. Spatial power delivery methods also play a crucial role in optimizing energy transmission by adjusting transmission parameters based on the relative position of transmitters and receivers, ensuring reliable and consistent performance in dynamic environments. Applications of integrated WPT-IT systems span various sectors. In consumer electronics, these systems enable wireless charging of devices while maintaining high-speed data connectivity, eliminating the inconvenience of physical connectors and enhancing user mobility. Healthcare applications benefit from continuous operation of medical devices and implants through wireless power delivery, coupled with real-time data transmission for remote monitoring and diagnostics.
