An example device includes a nanovoided polymer element, a first electrode, and a second electrode. The nanovoided polymer element may be located at least in part between the first electrode and the second electrode. In some examples, the nanovoided polymer element may include anisotropic voids. In some examples, anisotropic voids may be elongated along one or more directions. In some examples, the anisotropic voids are configured so that a polymer wall thickness between neighboring voids is generally uniform. Example devices may include a spatially addressable electroactive device, such as an actuator or a sensor, and/or may include an optical element. A nanovoided polymer layer may include one or more polymer components, such as an electroactive polymer.

This present invention discloses kits, solutions, and methods for regenerating a hydrogel coating on a hydrogel coated medical device. The solution comprises a first hydrophilic polymer and a second hydrophilic polymer. The reaction of the first and second hydrophilic polymers with the originally coated surface of the medical device forms an at least partially covalently crosslinked hydrogel layer. The solution may be part of a kit, wherein the first and second hydrophilic polymers are provided separately with or without the medical device included in the kit. The originally coated surface of the medical device has an initial thickness before use or wear and a second thickness before use or wear, the second thickness being less than the first thickness. Treatment of the hydrogel coated medical device with the solutions described herein increased the second thickness to approach a final thickness that is substantially equal to the initial thickness.
