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.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
