Recently, an indentation approach has been demonstrated to quantify the poroelastic relaxations of hydrogels. Although the approach has been demonstrated to quantify the transport properties of thick hydrogel materials, its relevance for thin hydrogel layers and other hydrated polymer membranes have yet to be explored. In this work, we demonstrate POroelastic Spherical Indentation Testing (POSIT) in quantifying the transport properties for model thin swollen polymer network based on poly(ethylene glycol) (PEG) hydrogel layers.
