论文摘要
我们建议可以通过使用称为液晶弹性体（LCE）的橡胶网络来控制，富集和放大气球。首先，LCE是有前途的人造肌肉，显示出对热和光的响应较大的自发变形。在LCE气球中，自发变形可以触发经典的气球，无论是相位分离（恒定体积）还是体积跳跃（在恒定压力下），从而大大放大了致动菌株。其次，即使在恒定温度下，LCE也具有不寻常的力学，而列明主管在弹性体内旋转的变形软模式也增加了。这些软模式丰富了LCE气球的力学，在经典的不稳定性期间，或作为单独的前护士在旋转状态和无脊椎状态之间也可以“气球”，从而导致通货膨胀期间连续不稳定性。
We propose that ballooning can be controlled, enriched and amplified by using rubbery networks of aligned molecular rods known as liquid crystal elastomers (LCEs). Firstly, LCEs are promising artificial muscles, showing large spontaneous deformations in response to heat and light. In LCE balloons, spontaneous deformations can trigger classic ballooning, either as phase-separation (at constant volume) or a volume jump (at constant pressure), resulting in greatly magnified actuation strains. Secondly, even at constant temperature, LCEs have unusual mechanics augmented by soft-modes of deformation in which the nematic director rotates within the elastomer. These soft modes enrich the mechanics of LCE balloons, which can also "balloon" between rotated and unrotated states, either during the classic instability, or as a separate pre-cursor, leading to successive instabilities during inflation.
