Abstract
An adhesive device comprising a microstructure and polymer designed to interdigitate with the surface structure of a target surface. The device may include a microstructure material having an elastomeric, crosslinked polymer which may swell in the presence of a liquid. In the pre-swell state, the device microstructure may interdigitate with a target surface microstructure. When liquid on the target surface contacts the microstructure surface of the device, the liquid may cause the microstructure surface of the device to swell. The swelling may cause the microstructure to grasp the target surface resulting in adhesion between the device and the target surfaces.
