![]() ![]() Here, we report light-fuelled self-oscillators based on liquid crystal network actuators that can exhibit three basic oscillation modes: bending, twisting and contraction-expansion. However, most of the self-oscillators are based on bending deformation, thereby limiting their possibilities of being implemented in practical applications. heat, light and chemicals, showing great potential for applications in power generation, autonomous mass transport, and self-propelled micro-robotics. Stimuli-responsive materials allow creating synthetic self-oscillators fuelled by different forms of energy, e.g. It occurs commonly in nature, a few examples being heartbeat, sea waves and fluttering of leaves. Self-oscillation is a phenomenon where an object sustains periodic motion upon non-periodic stimulus.
