Under the auspices of DARPA’s Integrity and Reliability of Integrated Circuits program, researchers from the Naval Surface Warfare Center (NSWC) and Air Force Research Laboratory (AFRL) are collaborating in powerful new ways to determine the reliability and integrity of microchips embedded in the some of the nation’s most critical military weapon and cyber systems.

State-of-the-art military sensors today rely on “active electronics” to detect vibration, light, sound or other signals. That means they constantly consume power, with much of that power and time spent processing what often turns out to be irrelevant data. This power consumption limits sensors’ useful lifetimes to a few weeks or months when operating from state-of-the-art batteries, and has slowed the development of new sensor technologies and capabilities. Moreover, the chronic need to redeploy power-depleted sensors is not only costly and time-consuming but also increases warfighter exposure to danger.

Many essential military capabilities—including autonomous navigation, chemical-biological sensing, precision targeting and communications—increasingly rely upon laser-scanning technologies such as LIDAR (think radar that uses light instead of radio waves). These technologies provide amazing high-resolution information at long ranges but have a common Achilles heel: They require mechanical assemblies to sweep the laser back and forth. These large, slow opto-mechanical systems are both temperature- and impact-sensitive and often cost tens of thousands of dollars each—all factors that limit widespread adoption of current technologies for military and commercial use.

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.
