  Nanomechanical systems offer a versatile platform for both fundamental
science and industrial applications. Resonating vibration has been demonstrated
to enable an ultrasensitive detection of various physical quantities, with
emerging applications including signal processing, biological detection and
fundamental tests of quantum mechanics. It has also been shown that the
mechanical vibration of a nanoscale cantilever can be used to detect
electromagnetic analogue-modulated waves. However, signals obtained with
nanoscale receivers are so weak that the data transfer often fails; to the best
of our knowledge, no successful practical demonstration has yet been reported.
Here, we present the first experimental demonstration of the use of
nanomechanical systems for digital data transfer with a digital image.
Furthermore, our fabrication method achieved a tiny gap around field emitter of
vibrational nano-antenna, which enables the receiver to work with quite a low
power consumption, on the order of 10nW.
