Flexible Mechanical Response Device With Optical Logic Emission Enabled by Synergistic Crystallization Engineering of Ester Polymer and Perovskite (Adv. Sci. 43/2025)

Flexible Mechanical Response Device This cover highlights a polymer–perovskite flexible device that converts motion progress and mechanical stress into optical logic. By harnessing ion–dipole interactions and crystallized space confinement, it achieves efficient exciton transfer for next‐generation sensing and wearable technologies. More details can be found in the Research Article by Chihaya Adachi, Ru‐Jong Jeng, Chi‐Ching Kuo, and co‐workers (DOI: 10.1002/advs.202508812).
