Biomaterials‐Based Hydrogel with Superior Bio‐Mimetic Ionic Conductivity and Tissue‐Matching Softness for Bioelectronics

Advanced Functional Materials, EarlyView.
By mimicking the ion‐accelerating effect of ion channel receptors in neuron membranes, a biomaterials‐based ionic hydrogel (BIH) is developed, which offers a high ionic conductivity of 7.04 S m−1, outperforming conventional chitosan, cellulose, agarose, starch, and gelatin based ionic hydrogels.

Hydrocolloid‐Based Multiwavelength Stretchable QD‐OLED Patch for Simultaneous Neonatal Jaundice and Dermatitis Treatment with Biosignal Monitoring

Advanced Healthcare Materials, EarlyView.
Comparison of therapeutic and diagnostic applications of a surface‐emitting light source with multiwavelength emission characteristics. Abstract Conventional light‐emitting‐diode‐based light sources suffer from rigidity, localized heating, and poor adaptability to skin deformation, limiting their use in skin‐attached medical devices.
