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
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
