Polyzwitterionic Organohydrogel and Soft Composite with Tunable Sol–Gel Properties Enabling On‐Demand Functionalization with Colloids

open access: yesAdvanced Science, Volume 13, Issue 12, 27 February 2026.
Poly[2‐(methacryloyloxy)ethyl]dimethyl‐(3‐sulfopropyl)ammonium hydroxide‐based organohydrogels are formed via nonsolvent‐induced gelation, featuring tunable viscoelasticity. Functional fillers (MXene nanosheets, magnetic NdFeB microparticles) enable electrical, magnetic, and mechanical responsiveness for applications in mechano‐tunable electromagnetic ...

Liquid Metal Elastomer Based Coplanar Waveguide Transmission Line for Stretchable and Self‐Healing RF Electronics

open access: yesAdvanced Electronic Materials, Volume 12, Issue 4, 18 February 2026.
This work shows the first proof‐of‐concept for fully self‐healing and stretchable coplanar waveguide (CPW) transmission line using printable electrically conductive liquid metal elastomer. RF performance was evaluated in frequency ranging from 1 to 6 GHz under uniaxial tensile strain up to 100%, after self‐healing, and for 1000 cyclic stretch‐release ...
