Abstract

In nature, many plants have evolved to disperse seeds via wind. Inspired by this, we have developed a microflier based on multi-responsive soft actuator. The soft actuator exhibits sensitive responses to various stimuli, including humidity, temperature, applied voltage, and light, resulting in significant deformation rates of up to 105°/s. When exposed to light, the microflier opens its fiberglass “pappus” during descent, increasing air drag and prolonging falling time by 105 %. By adjusting the deformation angle of the “pappus” under different light intensities, the terminal falling velocity of the microflier can be easily controlled. Importantly, due to the excellent aerodynamic characteristics, the designed microflier is capable of achieving wide-area dispersion with the assistance of slight air currents. These results provide new insights for the development of wireless controlled artificial microfliers and are crucial for applications such as environmental monitoring and large-scale distributed data collection.

多响应微型飞行器的灵感来自风传播的种子

在自然界中，许多植物已经进化到通过风传播种子。受此启发，我们开发了一种基于多响应软致动器的微型飞行器。软致动器表现出对各种刺激的敏感响应，包括湿度，温度，施加电压和光线，导致高达105°/s的显着变形率。当暴露在光线下时，微型飞行器在下降过程中打开玻璃纤维“pappus”，增加空气阻力并延长下降时间105% %。通过调整“pappus”在不同光强下的变形角度，可以很容易地控制微飞片的终端下落速度。重要的是，由于优良的空气动力学特性，所设计的微型飞行器能够在轻微气流的帮助下实现广域弥散。这些结果为无线控制人工微飞行器的发展提供了新的见解，对于环境监测和大规模分布式数据收集等应用至关重要。
