Robust Polymer Hydrogels Improve Electric‐Fish‐Inspired Batteries

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Electric‐fish‐inspired hydrogel batteries based on ion‐concentration gradients offer an attractive route to soft power sources; however, the poor mechanical properties of existing hydrogels limit device assembly and performance. Here, we report poly(ethylene glycol) methyl ether acrylate hydrogels that enable ion‐gradient batteries composed of

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

open access: yesAdvanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.
