Figure 1. Metamaterials were prepared in 3 x 3 and 5 x 5 unit cells through the use of a 3D printer. Incorporation into Type I/II Portland cement and water led to the production of concrete that exhibits triboelectric properties and has potential for use in intelligent infrastructure systems, including the ability to communicate with electric vehicles. Figure courtesy of the University of Pittsburgh.
