From the idea that the material with perovskite structure is known to have more effective piezoelectric characteristic compared to that with wurtzite structure, Barium titanate ( BaTiO 3 ) nanowire has been also studied by Professor Min-Feng Yu of University of Illinois at Urbana Champaign.

A "'perovskite "'is any material with the same type of crystal structure as calcium titanium oxide ( CaTiO 3 ), known as the " perovskite structure ", or XII A 2 + VI B 4 + X 2 " 3 with the oxygen in the cuboctahedral coordination.
