By combining complementary mindsets on the leading edges of electronic and radiofrequency device engineering, a pair of researchers in DARPA’s Young Faculty Award program have devised ultratiny, electronic switches that approximate inter-neuron communication. These highly adaptable nanoscale switches can toggle on and off so fast, and with such low loss, they could become the basis of not only computer and memory devices but also multi-function radiofrequency (RF) chips, which users might reprogram on the fly to behave first like a cell-phone’s signal emitter but then, say, as a collision-avoidance radar component or a local radio jammer.

Solid-state electronics began to overtake vacuum tubes in radios, computers and other electronic and radio frequency gadgetry more than 60 years ago. Now we live in a Silicon Age. Even so, vacuum electronic devices, whose origins date to the 19th century, touch our lives every day.

Demand for specialized integrated circuits for military electronics continues to surge exponentially with no end in sight. Systems that synchronize the activity of unmanned aerial vehicles; real-time conversion of raw radar data into tactically useful 3-D imagery; and instant access to high-resolution sensor feeds on the battlefield are only three examples of this reality.

See that black speck on the Lincoln’s penny-minted nostril? And on the right, notice another three of those specks comfortably framed by the eye of a needle? Those semiconductor chiplets, or “dielets” as DARPA Program Manager Kerry Bernstein calls them, could become Lilliputian electronic tamper-watching sentinels affixed to virtually every chip built into commercial and military systems.

Since the advent of the integrated circuit in 1958, the same year the Advanced Research Projects Agency was established, engineers have been jamming ever more microelectronic integration into ever less chip real estate. Now it has become routine to pack billions of transistors onto chips the size of fingernails.
