Using technology developed for its high end cars like the 370z , Murano and the X-Trail ; Nissan has managed to develop an iPhone case which can heal itself on being chipped.
The science behind the seemingly magical case is that polyrotoxane , the material used for making the case automatically reacts to chips and fill in the gaps due to its molecular structure. The iPhone case is made from ABS plastic to create a tight and rigid case, and its coated with Scratch Shield paint. The scratch resistant paint creates a better grip to hold the handset. Nissan is currently testing the case with a few journalists and a group of beta customers.
