Each module will connect to the other working parts through capacitive interconnects, which are essentially wireless pads that are smaller than standard pins. The modules are held together by electropermanent magnets and act as a toggle switch, thus allowing a user to easily turn that element on and off. Cameras, antennas, batteries, processors, and anything that can be fit into a module shell will be available. The shells of those modules can be 3D printed to a user's specified design.
"We want it to be like an app store," said Kaigham Gabriel, deputy director of Google's Advanced Technology and Projects Group, which developed the concept for the phone. "You may want a blood-sugar monitor and a cigarette lighter on your phone. Why should you not have that?"
