Abstract
Fiber-based sensors, owing to their high flexibility, excellent breathability, and ease of integration into everyday clothing, have the potential to serve as a novel type of wearable electronic device. This paper presents a helical strain-sensing fiber using electromagnetic induction, made from Ecoflex and magnetic nanoparticles. It achieves up to 2485% strain and maintains stable voltage output (max 90 μV) over 2000 cycles. In conclusion, based on this novel intelligent sensing material, we developed a human–machine interaction (HMI) system operable underwater, enabling remote control of a submarine model through hand gestures. This system facilitates real-time gesture interaction, opening new research avenues for the development of wearable HMI systems and Internet of Things technology in the future.
