Intrinsically stretchable devices often suffer from non‐uniform strain distributions under direct‐stretching conditions due to their large‐scale, patterned designs, leading to inconsistent performance. To address these issues, mechanochromic materials—substances that change color in response to strain—for precise and intuitive strain monitoring are employed. Leveraging this data, strategic design modifications, including extrinsic techniques such as rigid‐island with soft‐substrate and kirigami cuts are implemented, to mitigate strain non‐uniformity. Thus, highly desired uniform and homogenous strain control in a multi‐pixel stretchable system is achieved. By integrating these strain‐stopping with uniform strain control methods into arrays of rigid and soft chiral liquid crystal elastomers (CLCEs), effective color separation is demonstrated for encrypted information with enhanced strain uniformity and strain control. Additionally, the dynamic optical selectivity of circularly polarized light (CPL) of the CLCEs under specific conditions is explored, using uniaxial stretching to achieve both optical color changes and refined CPL separation. Consequently, leveraging the inherent optical properties of CLCEs, a uniform and highly functional multi‐pixel operating stretchable system is devised. The application of these extrinsic strain control strategies not only resolves issues of strain uniformity but also advances the field of stretchable smart materials, offering new possibilities for dynamic color‐ and polarization‐separating based on encrypted applications.

使用 Kirigami 切割和刚性应变抑制器进行颜色和极化分离加密的本征可拉伸机械变色材料中优化和均匀的应变控制


由于其大规模的图案化设计，本质可拉伸器件在直接拉伸条件下经常会出现不均匀的应变分布，从而导致性能不一致。为了解决这些问题，采用了机械变色材料（响应应变而改变颜色的物质）进行精确和直观的应变监测。利用这些数据，实施战略设计修改，包括外在技术，例如具有软基板的刚性岛和折纸切割，以减轻应变不均匀性。因此，在多像素可拉伸系统中实现了非常理想的均匀和均匀的应变控制。通过将这些应变停止与均匀应变控制方法集成到刚性和软质手性液晶弹性体 （CLCE） 阵列中，证明了加密信息的有效颜色分离，增强了应变均匀性和应变控制。此外，还探索了特定条件下 CLCE 圆偏振光 （CPL） 的动态光学选择性，使用单轴拉伸实现光学颜色变化和精细的 CPL 分离。因此，利用 CLCE 固有的光学特性，设计了一种均匀且功能强大的多像素操作可拉伸系统。这些外在应变控制策略的应用不仅解决了应变均匀性问题，而且推动了可拉伸智能材料领域的发展，为基于加密应用的动态颜色和极化分离提供了新的可能性。
