In an embodiment, a device comprises an active material. Activation of the active material causes deformation within the device to conform to and/or retain an object without engaging the object below a surface of the object. In another embodiment, contact with an object causes deformation within the device to conform to and/or retain the object. In yet another embodiment, an object holder can comprise: a recess, a cover disposed over the recess, and a switch configured to cause the active material to retain a deformed shape in the recess. The cover comprises an active material. The active material is configured to deform into the recess when contacted with an object.
