A review of humidity-driven actuator: toward high response speed and practical applications
Source abstract
Abstract
In the past two decades, humidity actuators have received extensive attention from researchers due to their merits of simple stimulation, no pollution, programmable actuation behaviour, and simple structure. However, in order to perform more complex and difficult tasks, it is indispensable to enhance the response speed of the humidity actuators. Therefore, we mainly discuss the influence of materials and structure on the response speed of the actuators in this paper. In this review, the materials of the actuators include inorganic materials, polymers, biomaterials, hybrid materials, and structural materials. According to the structures, the actuators can be divided into monolayer film and multilayer film types. In addition, the applications of humidity-driven actuators in humidity detection, soft robot, self-power and medical equipment are introduced, providing a reference for the large-scale application of humidity actuators. Finally, this review also considers the practical challenges faced by humidity-driven actuators, summarizes how these challenges affect the potential applications of the actuators, and prospects for the future development trend of the actuators.
