Abstract
A multilayer device comprised of at least one layer of material which is capable of absorbing liquid to thereby increase the volume of the layer, i.e., liquid swellable, and when bound to at least one non-absorbing or lesser absorbing layer of material causes deformation of the device upon liquid absorption.
