Design engineers are likely to create a host of new applications for microelectromechanical systems (MEMS). So predicts a panel of the Commission on Engineering and Technical Systems of the National Research Council. But first, its study says, more R&D must be launched and completed. MEMS can produce tiny 3-D mechanical structures using lithography techniques derived from the construction of integrated circuits. Instead of handling only electrical signals, MEMS merges signal processing with sensing and actuation. Some systems have moving parts. Thus, MEMS makes possible miniature fluid-pressure and flow sensors, accelerometers, gyroscopes, and micro-optical devices. The panel recommends enlarging R&D into MEMS-related fields, including surface materials, etching, packing, assembly, and engineering standards. CAD tools familiar in the design of integrated circuits are needed for MEMS, the study adds. Included are schematic-to-layout generation, automatic routing, and design verification. The result, the study says, could be "a revolution" of MEMS into medicine, robotics, navigation, computers, auto safety, munitions, instrumentation, and many other fields.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
