Encapsulated Organohydrogel Couplants for Wearable Ultrasounds (Adv. Electron. Mater. 10/2025)

Wearable Ultrasounds In article number 2400961, Zhuo Li and co-workers present an elastomer-encapsulated organohydrogel couplant designed for long-term wearable ultrasound imaging. By adding an appropriate amount of glycerol and employing elastomer encapsulation, the couplant effectively maintains long-term water retention. Meanwhile, the synergistic combination of glycerol and prefabricated hydrogel templates produces a smooth elastomer–organohydrogel interface, ensuring highly effective long-term ultrasound monitoring.
