Research progress on humidity-responsive fiber fabric-based artificial muscles
Humidity-responsive fiber fabric-based artificial muscles represent a class of materials that exhibit sensitive actuation properties in response to changes in wet environments.Their motion behaviors originate from structural transformations undergone by the fiber fabric under humidity stimuli.This type of artificial muscle plays a pivotal role in various application fields,including soft robotics and smart textiles.Depending on configuration differences,the muscles are primarily categorized into four types:pure fiber,composite fiber,host-guest structure and sheath struc-ture.This article briefly summarizes their current research status introduces the construction principles and structural characteristics of these four types of materials,and further analyzes their advantages and disadvantages in terms of performance.The analysis indicates that the pure fiber type is simple and practical,the composite fiber type exhibits superior performance,the host-guest structure type demonstrates ingenious design,and the sheath structure type is stable and relia-ble.On this basis,the future development trends are envisioned,highlighting the need for fur-ther research and improvement in areas such as stability,response speed,autonomous regulation capabilities,and multiple stimulus responses.This article provides scientifically meaningful ref-erences and inspirations for further research in this field.
