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.
For decades scientists have wondered whether electromagnetic waves might play a role in intra- and inter-cell signaling. Researchers have suggested since the 1960s, for example, that terahertz frequencies emanate from cell membranes, but they’ve lacked the technology and tools to conduct reproducible experiments that could prove whether electromagnetic waves constitute purposeful signals for biological function—or if they’re merely background noise. With recent advances in technology and modeling, experiments may now be possible to test signaling hypotheses.
DARPA published its Young Faculty Award (YFA) 2018 Research Announcement today, seeking proposals in 26 different topic areas—the largest number of YFA research areas ever solicited.
