STAR-RIS with energy harvesting from RF signals and vibrations
摘要
This paper presents a novel approach to simultaneous transmitting and reflecting (STAR) reconfigurable intelligent surfaces (RIS) for energy harvesting from both radio frequency (RF) signals and vibrations. STAR-RIS technology aims to enhance wireless communication networks by integrating communication and energy harvesting capabilities into a single platform. The proposed system utilizes a RIS that not only transmits and reflects RF signals for communication purposes but also captures and converts ambient RF energy and mechanical vibrations into usable electrical power. This dual-mode operation significantly improves the overall energy efficiency of the system. By leveraging the interaction of RF signals and mechanical vibrations, the design offers a promising solution for sustainable wireless networks, reducing the dependence on traditional power sources and enhancing the autonomy of wireless devices. The paper investigates the optimization of energy harvesting from these two sources, modeling the performance of the system in various operational environments, and demonstrates the potential for widespread application in next-generation wireless communication infrastructures.
