Dr. Seok Kim from the University of IL has developed a removable and reusable dry adhesive for wall hanging applications. This invention uses a shape memory polymer and internal heating coil to change the SMP's adhesion characteristics. In 10 seconds it can change states, thus altering its adhesion characteristics. It can be attached to accessories, like a hook, that are attached to walls in order to hang objects on. Due to the SMP's surface, the adhesive does not pick up debris or degrade over time. This adhesive leaves no residue.
