Abstract
En 中文
Soft machines crafted from stimuli-responsive materials hold great potential for intelligent autonomous systems. To stably generate a self-sustainable motion under constant stimuli, it is essential to overcome the challenges of geometric design, physical modeling, and mechanical-guided parametric study. Here, inspired by the classical M & ouml;bius strip, a threefold M & ouml;bius machine made from humidity-responsive agarose films is proposed. A theoretical model is built based on moisture diffusion and developable surface to unveil the mechanisms of curvature-driven rotary motion with shape conservation, and to establish the quantitative correlations between the motion speed and the geometric and environmental parameters to optimize the design under given constraints. As a result, a M & ouml;bius machine capable of operating in a constant humid environment for 252 hours is developed. It can also continuously output mechanical work and sense ambient humidity. It is envisaged that T the integration of intelligent structural design principles and physical modeling will push the development of innovative robotic systems to the next level.
