开发适用于可穿戴传感器的刺激响应材料是一个尚未解决的关键挑战。液晶（lc）尤其有前途，因为它们不需要电力，重量轻，并且可以调整以响应一系列目标化学刺激。本文报道了用于化学传感器的LCs设计的一项进展，发现LCs在自由表面上假设平行方向，但仍保持其化学响应性。由此产生的基于LC的传感器比以前的LC传感器设计更敏感，反应更快。
The development of stimuli-responsive materials suitable for use in wearable sensors is a key unresolved challenge. Liquid crystals (LCs) are particularly promising, as they do not require power, are light-weight, and can be tuned to respond to a range of targeted chemical stimuli. Here, an advance is reported in the design of LCs for chemical sensors with the discovery of LCs that assume parallel orientations at free surfaces and yet retain their chemoresponsiveness. The resulting LC-based sensors are more sensitive and exhibit faster responses than previous LC sensor designs.
