Holographic polymer-dispersed liquid crystal reflective structures have been formed using a highly elastic photopolymer. The elasticity allows for mechanical tuning of the reflection notch by over 120 nm in the visible spectral range using compressive stress. The shift in the central position of the reflection notch is related to the strain in the system and an effective elastic modulus for the structure is obtained.

    The flow-induced transition of liquid crystalline polymers (LCPs) is studied by rheological techniques. Aqueous solutions of hydroxypropylcellulose (HPC) in water are adopted as a model LCP system. Nonisothermal oscillatory tests are first used to quantitatively determine the "rheological" phase...

    In most industrial robots, serious problems of vibratory behavior are caused because of elasticity in the drive systems. An electro-rheological (ER) fluid is a substance that can change its apparent viscosity by the application of an electric field, and homogeneous ER fluids are effective in...
