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
Design engineer compensation varies widely by location. If you live in Boston, your salary will average more than $90,000, nearly $20,000 above the national average. But if you live in Cleveland, your salary will average almost $10,000 below the national average.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
For many years, it was believed that the strongest biological substance on Earth was spider silk, but new research says aquatic snails produce an even stronger material that could disrupt manufacturing forever.
Most everyone thinks they are ready for an emergency or a disaster. Most everyone is wrong. But engineers are a unique position here as both the designers and beneficiaries of emergency preparedness systems.
