Strain‐Responsive Circularly Polarized Luminescence in Cholesteric Liquid Crystal Elastomers through Laser‐Engineered Microstructures (Adv. Funct. Mater. 30/2026)

Key Points

• The research aims to develop a strain-sensing system using cholesteric liquid crystal elastomers and quantum dots.
• Engineered porous cholesteric liquid crystal elastomers using a femtosecond laser.
• Coated the CLCEs with quantum dots to enhance photoluminescence.
• Assessed the dual-color response of CLCEs under mechanical stress.
• The engineered CLCEs exhibited a vivid and sensitive dual-color response to mechanical stress.
• The interaction between the structural color and photoluminescence created a distinctive visual effect.
• Demonstrated potential for advanced anti-counterfeiting applications through enhanced visibility.
