Therefore, hygroscopic materials such as hydrogels, which effectively absorb water, significantly enhance the electrical performance of HEGs. Through meticulous discussion, Il-Doo Kim and co-workers present in article number 2301080 various considerations, including the selection of nanomaterials, mechanisms, electrode design, and form factors, for the development of high-performance HEGs. In particular, the authors elucidate the pivotal role and application strategies of hygroscopic materials. Volume36, Issue12Hygroscopic MaterialsMarch 21, 20242470089 RelatedInformation
