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
Major changes are happening in the world of 3D printing and additive manufacturing materials, machines, and software. If the industry -- and the design engineers and OEMs it serves -- are to grow, all three areas must become much more tightly integrated.
Americans spent more than $60B on their pets in 2015. Folks are definitely spending their money on more than dog food. We’re spending on things like dog spas and fancy toys, and as you can imagine, the wearables market is becoming well represented here.
Time was when sports equipment was made only from common, everyday, low-tech materials. But now sports equipment has a new, high-tech ingredient that is helping players take their game to the next level.
