Abstract: "We have developed a nanowire nanogenerator that
is driven by an ultrasonic wave to produce continuous direct-current
output. The nanogenerator was fabricated with vertically aligned zinc oxide
nanowire arrays that were placed beneath a zigzag metal electrode with a
small gap. The wave drives the electrode up and down to bend and/or vibrate
the nanowires. A piezoelectric-semiconducting coupling process converts
mechanical energy into electricity. The zigzag electrode acts as an array
of parallel integrated metal tips that simultaneously and continuously
create, collect, and output electricity from all of the nanowires. The
approach presents an adaptable, mobile, and cost-effective technology for
harvesting energy from the environment, and it offers a potential solution
for powering nanodevices and nanosystems."
