Considering the energy efficiency and communication complexity of our distributed approaches I and II and the same simulation setting, Figure 5(a) shows the total dissipated energy in nanojoule (nJ) per number of nodes (the average energy dissipation per node).
This product range enables measurement of the energy/pulse or average power of pulsed lasers from the nanojoule to the multi-joule level over wavelengths ranging from the deep ultraviolet through the far infrared and from single pulses to repetition rates of 10 kHz (with measurement of every pulse).
The current pules energy created with each polarity change (almost 200 nanojoules per pulse) is sufficient to energize a low-power counter circuit that records the rotation count.
Spot size was 3 [micro]m for the lamellar cut and 2 [micro]m for the side cut; the energy level was adjusted to 140 nanojoules (nJ).
"The beauty of the new wireless sensing devices is that they are so small they only need nanojoules of energy to operate, and with ultralow power radios that take only low milliamps, single digit, we're looking at this kind of thing" Butler says.
