WebPhotodriven Self-Excited Hydrogel Oscillators. Chen Xuan, Yu Zhou, Yusen Zhao, Ximin He, Lihua Jin. Stimuli-responsive materials are designed for self-sustained soft robots. Using a photothermally responsive hydrogel cantilever as a model system, this paper investigates the mechanism and energy flow in self-excited oscillation under a constant ... WebWhen a photo-responsive hydrogel cantilever vibrates under a fixed light source, a periodic photo moment is imposed on the cantilever by the ever-switching light incidence between the top and bottom surfaces. The photo moment is induced by a diffusion driven inhomogeneous distribution of water concentration through the cantilever's thickness. …
