Millimeter-scale hydrogels form reversible, stimulus-responsive assemblies that encode high-density data, offering a dynamic alternative to static printed codes for adaptive information storage.

Stimuli-responsive hydrogels not only express excellent biocompatibility, but also can respond when exposed to external stimulation, enabling a wider range of applications in biomedicine. However, at ...

Flexible electronics have been drawing significant attention for healthcare applications and show great promise for monitoring of blood circulation (e.g., postoperative monitoring of free flaps).

A light- and temperature-responsive hydrogel combines MXene and PNIPAM to achieve reversible, high-performance EMI shielding across a wide GHz range. (Nanowerk Spotlight) The rapid growth of wireless ...

Early smart materials were typically amorphous polymers, hydrogels, or liquid crystalline systems with randomly distributed responsive groups, which limited response speed, energy efficiency, and the ...

Within tissues, cells are embedded in complex, three-dimensional structures known as the extracellular matrix. Their biomechanical interactions play a crucial role in numerous biological processes.

Hydrogels are 3D networks of hydrophilic polymers that can absorb and retain large amounts of water due to physical or chemical cross-linking of individual polymer chains. However, poor mechanical ...

From ultra-sensitive sensors to shape-shifting implants, stimuli-responsive smart materials react reversibly to heat, light, stress, or pH. They could transform devices and therapies once issues in ...
