As electronics devices become smaller and smaller, the challenges faced when designing them become questions of scale. Semiconductors, for example, have a thin, 35-angstrom layer of silicon dioxide used as an insulating material. As the chips get smaller, the insulating material must also proportionally shrink. But once the thickness falls below 20 angstroms, the silicon layer is no longer an effective insulator. Researchers at Motorola, Pacific Northwest National Labs, and Oak Ridge National Lab (ORNL) are joining forces for development of new insulating materials from crystalline oxides on silicons that are expected to have higher dielectric strengths and higher capacitance. "We are able to eliminate one of the hurdles to continuing the current rate of growth in the semiconductor industry," says Rodney McKee, a researcher at ORNL Metals and Ceramics Div. "If Moore's Law continues to hold true, we'll need the new insulating materials in just a few years." For more information, call Jan Haerer at (865) 241-7613.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
