Structure and Wiring Optimized TT/MT Double‐Helical Fiber Sensors: Fabrication and Applications in Human Motion Monitoring and Gesture Recognition

Advanced Science, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 4, 2025

Abstract A fibrous flexible sensor, with its small size, minimally burdens the human body, ranking among most user‐friendly sensors. However, application is often limited by damage caused electrode movement, as sensors are typically attached to joints, which can be greatly alleviated placing two electrodes on same side. Inspired hydrogen bonds in double‐helical structure of DNA, design commonly found and applied fiber‐based batteries supercapacitors into through coaxial wet‐spinning further treatment. The double helical sensor exhibits high strength maintains stable operation prepared under over 300% strain gauge factors (GF) 0.9, 39.5, 349, respectively, working ranges. This unique single‐sided also enabled applications such water flow sensing. a smart glove capable real‐time integrated, five‐channel finger motion detection, used convolutional neural network (CNN)‐based machine learning algorithm achieve 98.8% accuracy recognizing six common gestures. study provides novel approach optimize distribution an internally encapsulated structure, making significant contribution field

Humans possess an innate ability to perceive a wide range of objects through touch, which allows them interact effectively with their surroundings. Similarly, tactile perception in artificial sensory systems enables the acquisition object properties, human physiological signals, and environmental information. Biomimetic sensors, as emerging sensing technology, draw inspiration from biological exhibit high sensitivity, rapid response, multimodal perception, stability. By mimicking mechanisms microstructures, these sensors achieve precise detection mechanical thereby paving way for advancements applications. This review provides overview key mechanisms, microstructure designs, advanced fabrication techniques biomimetic sensors. The system architecture design is also explored. Furthermore, highlights significant applications recent years, including texture recognition, health detection, human–machine interaction. Finally, challenges future development prospects related are discussed.
