Non-Hermitian Skyrmion for All-In-One Devices: Wireless Power Transfer, Sensing, and Communication

Optical skyrmions, characterized by their unique topological field configurations and intrinsic stability, offer a transformative foundation for next-generation technologies. Besides fundamental studies often prioritized in skyrmion research, we focus on the distinctive multi-eigenfrequency characteristics and field distributions of skyrmion resonance modes within a non-Hermitian framework, leading to the creation of a integrated near-field platform that simultaneously delivers wireless power transfer, high-fidelity wireless communication, and precision wireless sensing. Crucially, this integrated approach overcomes key limitations in conventional near-field electromagnetic systems. The conflict of different applications within compact architecture and robust, high-effective method is satisfied by two synergistic mechanisms: 1) robust, multi-channel wireless communication inherently supported by the skyrmion resonant structure and 2) efficient power transfer and ultra-sensitive detection driven by exceptional point. This unprecedented integration directly addresses in demanding scenarios, such as minimally-invasive and implantable biomedical devices, where size constraints, functional complexity, and operational reliability are paramount. Our work not only advances fundamental understanding of controllable topological photonics but also demonstrates the remarkable versatility and practical utility of skyrmion-based architectures in complex real-world needs, establishing a novel paradigm for the development of highly integrated and robust near-field technologies.
