Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation
Advanced Functional Materials, EarlyView.The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking
Advanced Functional Materials, EarlyView.This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.
