As researchers like Dr. Palacios see it, two-dimensional materials will be the linchpin of the internet of everything. They will be “painted” on bridges and form the sensors to watch for strain and cracks. They will cover windows with transparent layers that become visible only when information is displayed. And if his team’s radio wave-absorber succeeds, it will power those ever-present electronics. Increasingly, the future looks flat.
