In this paper, novel ultra-long aligned array of Barium Titanate (BaTiO3) nanowires (NWs) was used to fabricate piezoelectric sensors and investigate their vibration sensing and energy harvesting potential. The acceleration sensing characteristics of the piezoelectric BaTiO3 NWs based sensor was presented by conducting vibration excitation experiments induced from an electromagnetic shaker. Two different top electrode configurations which include a melted Indium and a short cantilever Indium beam located over the BaTiO3 NWs surface were utilized to study the acceleration sensing and energy harvesting scope respectively. The results shown validate their excellent energy conversion capabilities and demonstrate linear behavior over a wide frequency spectrum which elucidates their potential to be developed as advanced sensors and high efficiency vibrational energy harvesting devices.
