Abstract
The present invention relates to piezoelectrie energy conversion assemblies. The assembly includes a piezoelectric nanowire (such as a ZnO nanowire), an electrically conductive nanofilament (such as a carbon nanotube), a first electrically conductive element (such as a first metallic trace), and a second electrically conductive element (such as a second metallic trace). The first electrically conductive element is electrically connected to the piezoelectric nanowire, and the second electrically conductive element is electrically connected to the electrically conductive nanofilament. The piezoelectric nanowire and electrically conductive nanofilament are operable to contact one another such that a charge can flow from the first electrically conductive element, through the piezoelectric nanowire and the electrically conductive nanofilament, to the second electrically conductive element. Generally, the piezoelectric nanowire and/or electrically conductive nanofilament are cantilevered to allow them to contact one another. Assemblies can be arranged in series or in parallel.
