High‐Speed Microscopy and Optofluidic Modulation of Dynamic Oscillations in Liquid Metal Microdroplets (Adv. Mater. Technol. 19/2025)
Year: 2025
Type: article
Abstract: Optofluidic Oscillators In their Research article (10.1002/admt.202500910), Jing Zeng, Wen Fan, and co-workers utilize smartphone-assisted high-speed microscopy (up to 7680 fps) to visualize the self-sustained oscillations of EGaIn microdroplets partially immersed in HCl. The asymmetric cycles involve rapid oxidation-driven contractions followed by slower recovery mediated by acid-induced oxide dissolution. Janus EGaIn–HCl droplets autonomously modulate laser reflections and interference patterns, enabling programmable optofluidics and adaptive photonics.
