Abstract

Creating flexible actuators that mimic natural organisms' movements and respond to various stimuli is highly significant for bionic soft robotics, electronics, and wearables. However, achieving a simultaneous response to multiple stimuli within a single actuator still has great challenges in terms of structural design. Here, by combining carbon nanotubes with high photothermal effect, bacterial cellulose with water-triggered expansion, and polyethylene with a large thermal expansion coefficient, a bilayer actuator is proposed with macroscopic and fast response to natural sunlight, low voltage, temperature, humidity, and organic solvents. Based on this, we propose a smart curtain that passively responds to light changes, lowering room temperature by 10.9°C to reduce the huge energy consumption for thermal management of buildings. Besides, a multi-stimulus response curtain that switches according to ambient humidity is designed. Interestingly, this soft actuator can also realize complex bionic motions such as bionic clamping, jumping, self-oscillation, and crawling.

一种多刺激响应驱动器，用于高效的热管理和各种仿生运动

创造灵活的执行器，模仿自然生物的运动，并对各种刺激做出反应，对于仿生软机器人、电子产品和可穿戴设备非常重要。然而，在结构设计方面，在单个执行器内实现对多个刺激的同时响应仍然存在很大挑战。本研究将具有高光热效应的碳纳米管、具有水触发膨胀的细菌纤维素和具有大热膨胀系数的聚乙烯相结合，提出了一种对自然光照、低电压、温度、湿度和有机溶剂具有宏观快速响应的双层致动器。基于此，我们提出了一种被动响应光线变化的智能窗帘，将室温降低10.9°C，为建筑的热管理减少巨大的能源消耗。此外，还设计了可根据环境湿度变化进行切换的多刺激响应幕。有趣的是，这种柔性驱动器还可以实现复杂的仿生运动，如仿生夹紧、仿生跳跃、自振荡、仿生爬行等。
