Abstract

Hydrogels that can swell and deswell under the influence of opposing external stimuli have frequently been reported as muscle-mimicking materials. However, the mechanism of such materials is markedly dissimilar to that of natural muscles. Natural muscles contract when fueled by ATP and spontaneously relax once ATP is completely consumed. The subtlety of this “self-resetting” mechanism is avoiding the equivalent opposite modulation to reset the size and shape of the muscle, which may easily result in the cumulation of action error after several repeating cycles. In this article, we fabricate a bilayer hydrogel actuator with the aid of the I2-responsiveness of poly(ethylene glycol)-based hydrogel. When this actuator is coupled with a reaction network containing NaIO3, NaI, and CS(NH2)2, which generates I2 as an intermediate product, it will temporarily deform and recover spontaneously with the consumption of I2. Such an actuator is highly similar to natural muscles in terms of the actuation mechanism. Several biomimicking functions were achieved by this actuator.

一个碘驱动的肌肉模拟自我重置双层水凝胶驱动器。
水凝胶在相反的外部刺激下可以膨胀和破裂,经常被报道为肌肉模拟材料。然而,这种材料的机制与天然肌肉明显不同。天然肌肉在受到ATP的刺激时会收缩,一旦ATP被完全消耗就会自动放松。这种“自我重置”机制的微妙之处在于避免了通过等效的反向调节来重置肌肉的大小和形状,这很容易导致几个重复周期后动作误差的累积。本文利用聚乙二醇基水凝胶的i2响应性制备了一种双层水凝胶致动器。当该致动器与含有NaIO3、NaI和CS(NH2)2的反应网络耦合时,产生中间产物I2,随着I2的消耗,该致动器会暂时变形并自发恢复。这种致动器在致动机制方面与天然肌肉高度相似。该驱动器实现了多种仿生功能。

期刊介绍: Materials Horizons is a leading journal in materials science that focuses on publishing exceptionally high-quality and innovative research. The journal prioritizes original research that introduces new concepts or ways of thinking, rather than solely reporting technological advancements. However, groundbreaking articles featuring record-breaking material performance may also be published. To be considered for publication, the work must be of significant interest to our community-spanning readership. Starting from 2021, all articles published in Materials Horizons will be indexed in MEDLINE©. The journal publishes various types of articles, including Communications, Reviews, Opinion pieces, Focus articles, and Comments. It serves as a core journal for researchers from academia, government, and industry across all areas of materials research. Materials Horizons is a Transformative Journal and compliant with Plan S. It has an impact factor of 13.3 and is indexed in MEDLINE.
