“…Multiple corridor whispering gallery modes can be excited with a variety of electrode combinations and through a simple digital tuning scheme to obtain different frequency outputs. Marcelli et al [62] redesigned triangular resonators with Scherbinsky geometry by fixing the base surface of the resonator and increasing the internal complexity, i.e. starting from the original all-metallic patch and changing to a triangular structure, to design triangular Scherbinsky resonators, which were connected to a unipolar two-pass RF MEMS switch to provide frequency tuning for K band potential applications.…”

Metaverse as a comprehensive integration of multiple digital technologies of the new generation, enables human beings to bring unprecedented immersive experiences with the support of virtual reality, augmented reality, blockchain, digital twin, Artificial Intelligence, haptic IoT, and human-computer interaction. In view of the urgent need for high-speed and high-capacity data transmission as well as high integration, RF MEMS devices have become the core components for metaverse system building due to their advantages of miniaturization, high integration, and low power consumption. Playing a pivotal role in real-time high-capacity data transmission and signal processing in metaverse interactive systems, the low cost and high performance of RF MEMS devices have once again become the focus of attention for people from all walks of life. Therefore, this paper focuses on the working principles and performance optimization of RF MEMS devices. Firstly, the classification and basic principles of RF MEMS devices are introduced, followed by the advanced fabrication technology and optimization scheme of MEMS devices, and then the advanced applications of RF MEMS devices in the field of metaverse are discussed in focus, including IoT mobile communication, Artificial Intelligence, and flexible wearables. Finally, the prospects and potential challenges for the development of RF MEMS devices interacting with the metaverse are summarized and discussed.

This paper proposes an array structure with multidirectional remanent magnetization based on hard-magnetic soft materials, which can be used as a soft switch array on planar and curved surfaces. We firstly investigate the displacement response of a hard-magnetic soft switch which is excited by a magnetic field, and related to the magnitude and direction of the magnetic field. When the remanent magnetization direction of the soft switch is opposite to the horizontal component of the magnetic field, the displacement response is greater than that of the driving magnetic field in other directions. The maximum displacement of the soft switch can reach 4.5 mm under a 6 V driving voltage applied to the Helmholtz coil. We further design 2 × 2 and 3 × 3 switch arrays and the circuit structures of the switch arrays. The switch arrays are fabricated, and the displacement responses of the switch arrays under different driving magnetic fields on planar and curved surfaces are finally demonstrated. When the Z-axis displacement of the device reaches more than 3 mm, the LED light can be switched on. The hard-magnetic soft switch array structure designed in this paper can enable the application of soft switches in curved environments, verifying the feasibility of the application of hard-magnetic soft switch arrays. It is expected to provide a guidance for the design and manufacturing of multi-functional hard-magnetic soft switches in the future and the application of hard-magnetic soft switch arrays in planar and curved environments.
