Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Bio‐Inspired Artificial Muscle‐Tendon Complex of Liquid Crystal Elastomer for Bidirectional Afferent‐Efferent Signaling

open access: yesAdvanced Materials, EarlyView.
The Muscle–tendon complex (MTC)‐inspired Liquid crystal elastomer (LCE) artificial muscle integrates actuation (efferent) and proprioceptive sensing (afferent) by combining contractile nematic and elastic isotropic LCEs within a single soft structure. Embedded liquid metal channels enable simultaneous Joule heating and real‐time sensing of length and ...

Colossal Cryogenic Electro‐Optic Response Through Metastability in Strained BaTiO3 Thin Films

open access: yesAdvanced Materials, EarlyView.
Utilizing the thermodynamic theory of optical properties, a colossal cryogenic electro‐optic response in BaTiO3 thin films is designed and demonstrated by stabilizing a low symmetry metastable monoclinic phase via epitaxial strain tuning with an electro‐optic response reaching ≈2516 pm V−1 at 5 K. This approach represents a new paradigm for engineering
