Abstract

A simple solution growth process was employed to deposit ZnO nanowires on carbon nanotubes and nano-structured carbon paper. Vertical ZnO nanowires formed on the carbon paper with a hexagonal orientation. On the carbon nanotubes, the ZnO nanowires and platelets integrated as an agglomerated sphere. Electric charge flow was measured in both structures upon probe contact, and would decay over several hours. A mechanical perturbation was found to recharge the structure, which was attributed to the piezoelectric ZnO nanowires. Continuous as well as intermittent vibration coupled with an electrochemical storage mechanism to create a perpetual current source.
