Very interesting research. Can one harvest any reasonable amounts of energy for self-powered wireless nodes in this way in the future?

It is interesting to see that piezo effect still exists in the 10 nm size regime. Usually due to the small size and large surface area the piezo effect is "relaxed" when the particle size is smaller than 10s of nanometers.

It will be interesting to see far reaching applications of this new concept and research. I am eager to know calibration aspect for these sensor systems. What will be typical accuracy and repeatability for these types of sensors? Can we employ them for high frequency or impulse input to sense mechanical shock?

The NWO will use nano sensors to secretly monitor every aspect of our lives.

The use of quantum dots as MEMS devices which produce electricity from motion or produce motion when electricity is applied provides a new domain for innovation. Quantum dots have already been in the news for their ability to produce pure colored lights (color wavelength depending on quantum dot dimensions) and for the potential of entangled quantum dots (qubits) in quantum computing devices. As we celebrate the 50th anniversary of laser, it is interesting to speculate where innovation in quantum dots may be leading us.
