MEMS (microelectromechanical systems) have the versatility to solve specialized problems, and the demonstration of that versatility continues at Sandia National Laboratories. Researchers there have devised an advanced gas-sampling procedure using picoliters of gas to check whether the atmosphere inside a MEMS device is pure.
A small commercial valve crushes a tiny object—the MEMS chip under
investigation—and feeds the released gases to a custom-built intake manifold.
Because the test mechanism requires only picoliters of gas, it can re-evaluate
dozens of times, using bursts of puffs of gas that it receives. This repetition
increases the final test's validity due to the repeated sampling and testing
during a 20-minute period, compared with the uncertain validity of a single test
The Smart Emergency Response System capitalizes on the latest advancements in cyber-physical systems to connect autonomous aircraft and ground vehicles, rescue dogs, robots, and a high-performance computing mission control center into a realistic vision.
