Tissue‐Adhesive Fabric‐Based Bioelectronics for Wearable and Implantable Applications

open access: yesAdvanced Functional Materials, EarlyView.
An implantable and wearable bioelectronic textile (iTextile) is introduced as a unified platform bridging wearable and implantable systems. By integrating a self‐healing polymer, stretchable silk fabric, conductive composite electrodes, and an adhesive hydrogel, the platform enables conformal, stable interfacing with soft tissues. The iTextile supports

Silicone Phase Behavior Resolves the Softness–Surface Functionality Trade‐Off in Emerging Stretchable Electronics

open access: yesAdvanced Functional Materials, EarlyView.
Ultrasoft silicone elastomers often sacrifice surface functionality for mechanical compliance. In Mold Star, low‐molecular‐weight species form a dispersed phase that weakens the network and passivates the surface. Solvent extraction removes this phase, unexpectedly improving both extensibility and metallization performance, enabling conductive ...
