Multidimensional, multilevel information storage and encryption in auxetic liquid crystal elastomers

Abstract: , during polymerization. The information is patterned using UV-masks that are designed to realize both 2D optical and 3D tactile information in the form of binary images and haptic Braille letters respectively. The addressing voltages are determined by measuring the elastic and dielectric properties of the precursor mixture and the auxetic strain threshold can be tuned between ∼0.58 ± 0.05 and ∼0.91 ± 0.05. The decryption processes for the optical and tactile information are independent and offer security through the need for strains of specific magnitudes and directions. This study represents an innovative approach for encryption of information utilizing a recently-discovered family of soft materials, auxetic liquid crystal elastomers.
