# Air-permeable hydrogels created by phase separation of aerogels

Researchers developed a new type of hydrogel that allows air to pass through by using a viscoelastic phase separation technique on aerogels. This innovation could improve wearable electronics and medical dressings by combining breathability with hydrogel flexibility. The method offers a way to integrate properties of both materials for advanced applications.
