虽然液晶研究在科学上已经有了很好的基础，但仍有一些令人兴奋的新系统出现，值得进行广泛的基础研究。其中一个领域是弯曲分子（所谓的“香蕉液晶”）的研究，它具有微妙的手性和极性特性。在本文中，我们表明这些材料还具有非常不寻常的流变特性，例如形成稳定的流体纤维和桥。在电场作用下，这些物体表现出显著的机械效应，如水平和横向振动。研究表明，香蕉液晶纤维的研究可能会导致新型的人工肌肉系统。
Although the liquid-crystal research is well established in science, there are newly emerging exciting systems, that deserve extensive basic studies. One of these areas is the research of the bent-shaped molecules (so-called "banana liquid crystals"), which have delicate chirality and polarity properties. In this paper we show that these materials also have very unusual rheological features, such as the formation of stable fluid fibers and bridges. Under electric fields, these objects present striking mechanical effects, such as horizontal and transversal vibrations. Studies indicate that the research of banana-liquid-crystal fibers may lead to new type of artificial muscle systems.
