Design and Fabrication of Highly Stretchable and Tough Hydrogels

Stretchable and tough hydrogels have attracted a lot of attention due to their great potential in applications such as wound healing, drug delivery, tissue culture, etc. They can also be paired with electronic components to create artificial skin, wearable electronics, and patches. To promote the development of more hydrogels, we will summarize methods and materials that have been used to develop these gels, and then we will compare the performance of these gels in an aim to guide the future development of gels for superior performance, especially for specific applications.
