This study explores improving strain uniformity in Chiral Liquid Crystal Elastomers (CLCEs) for use in stretchable electronics and imaging applications. It addresses the issue of non-uniform strain distribution with innovative design strategies. By incorporating mechanochromism, we demonstrate color separation based on the degree of strain, utilizing chiral structures to indicate displacement. We propose a novel solution using rigid plate and kirigami techniques to ensure uniform strain and color tuning across CLCE arrays. This approach is validated through Finite Element Method (FEM) and theoretical analysis. Our findings have significant implications for developing uniformly strain-controlled stretchable devices, with potential applications in camouflage and encryption, showcasing an effective method for manipulating strain and color in CLCE-based devices.
