Scientists at Penn State have developed a flexible, high-power hydrogel battery inspired by electric ...

Power sources used in devices found in or around biological tissue must be flexible and nontoxic, while still powerful enough ...

The ideal material for interfacing electronics with living tissue is soft, stretchable, and just as water-loving as the tissue itself--in short, a hydrogel. Semiconductors, the key materials for ...

Growing cells in the laboratory is an art that humans have mastered decades ago. Recreating entire three-dimensional tissues is much more challenging. Researchers are developing a new hydrogel-based ...

Hydrogels are characterized by their hydrophilic nature and 3D network structure, possessing the unique ability to absorb significant amounts of water or biological fluids. This feature makes them ...
