The active material of liquid crystal elastomer (LCE) is capable harvesting energy directly from the surroundings and sustaining continuous motion in presence light heat. It extensively employed machinery, soft robotics, biomedicine, other fields. To date, there barely any research on sustained chaotic system LCE pendulum. main objective this paper to put forward a simple pendulum comprising photosensitive LCE. In accordance with dynamic model, nonlinear model established, its behavior...
Self-sustained chaotic system has the capability to maintain its own motion through directly absorbing energy from steady external environment, showing extensive application potential in harvesters, self-cleaning, biomimetic robots, encrypted communication and other fields.
