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).
