项目标书摘要:Outline of Research at the Start:キラル液晶は,自己組織的に形成する3次元らせん配向によって特異な光学特性を示す。本研究では,液晶中で誘起される分子拡散をキラルネマチック液晶の光反射特性を利用して可視化することを目的とする。キラル液晶の光学特性がキラリティを誘起する分子の濃度に依存することを利用し,物質拡散を反射波長の変化から可視化するとともに,キラル剤濃度分布を能動的に制御してキラル液晶の3次元らせん配向を実現する。

    Sensing technologies capable of quantitatively measuring mechanical stress are essential in fields such as robotics. Here, we present a material that enables real-Time, electronic-free stress sensing through structural color changes. The material is a multilayered film incorporating chiral-nematic liquid crystalline elastomers (N∗ LCEs) which respond to mechanical deformation such as elongation and compression by altering their reflection color. N∗ LCEs exhibit both optical properties derived from their helical molecular organization and elasticity typical of rubber-like materials. Our system differs from conventional LCEs in that it features a multilayer architecture designed to independently control the relaxation dynamics of optical responses without requiring chemical modification. This design achieves both rapid response and reversibility which are vital for practical applications. For both elongation and compression, the applied strain can be quantitatively evaluated through reflection color shift. These findings highlight the material's potential for use in next-generation mechanoresponsive devices, including wearable sensors, structural health monitors, and intelligent robotic skins. © COPYRIGHT SPIE.
