Plasmon-mediated wavelength-selective photoactuation for multi-directional soft robots

초록

Light-driven soft actuators have been gaining attention in soft robots, although the challenges of accurately and reversibly modulating in various directions remains. Here we present a strategy for wavelength-selective photoactuation based on Au nanorod/reduced graphene oxide nanocomposites. The plasmonic characteristic of Au nanorods can induce strong photothermal conversion at different wavelengths depending on the aspect ratio of that. The reduced graphene oxides have high thermal conductivity and negative coefficients of thermal expansion, leading to significant bending in bilayer configurations. © 2023, META Conference.
