Abstract

Microwave-based wireless driving have garnered significant attention due to their penetration capability, selective heating, and medium heating properties. In multi-microwave actuator systems, selective control of actuators using microwave frequencies has emerged as a promising approach. Understanding the resonance mechanism of microwave actuators is key to implementing frequency-based control strategies for microwave driving. Herein, we analyzed the resonance condition of flexible microwave actuators composed of SMA springs and passive wires. We demonstrate the response characteristics of standalone SMA springs and the influence of passive wires on the SMA spring in a microwave field. We then analyzed the wire's equivalent antenna model and resonant length. We also evaluated the effects of SMA spring coil numbers and passive wire lengths on the actuator's resonant state at different frequencies (2.4 GHz, 4 GHz, and 5.9 GHz) and developed an equivalent model for the actuator. Our research provides insights for designing microwave actuators with different frequency responses and establishes a foundation for developing complex microwave robotic systems.

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
