Abstract A self-oscillating system can harness energy from the external environment to sustain its continuous motion, making it highly suitable for applications in soft robotics, military industry, energy, and other fields. This article introduces a composed of light-responsive liquid crystal elastomer fiber, baffle, spring, capable achieving self-oscillation under stable lighting conditions. Considering established dynamic model elastomers (LCEs), nonlinear is introduced used as basis exploring characteristics. Numerical computations reveal that coupled exhibits two distinct motion states: static states. The behavior sustained through interaction light damping dissipation. Furthermore, detailed investigation conducted on key parameters affecting frequency amplitude self-oscillation. In contrast complexity current systems, this particular features simplicity structure, ease manufacture, strong adaptability. These advantages are expected provide broader design possibilities micro-machines mechanical production processes.

Abstract The efforts in soft materials actuators that can generate driving deformation under external energy stimulation have promoted the rapid development miniature sized robotics. Recently, with continuous and autonomous actuation behavior constant are highly sought after. Light‐fueled self‐oscillators based on self‐shadowing effect triggered by their light‐induced provide an effective scheme. However, grand challenges remain light‐driven self‐actuators multi‐directional controllable operate low power density air. Here, this study reports a MXene‐based multilayer actuator generates self‐sustained robotic motion upon light intensity– 50 mW cm −2 (half Sun). self‐track sources continuously oscillate while incident angle is changed. exhibits high adaptation to types of sources, including inherence coherence different wavelengths. Diverse applications demonstrated, signal transmitter beam reflection, self‐propelled sailboat, light‐to‐mechanical motor, robots biomimetic movements. results offer new insights for light‐fueled controllability low‐intensity requirement its potential application prospect.
