Exploring Batteries for Micromachinery
Posted in News, Batteries, Electronic Components, Electronics on Friday, 03 October 2014
A team of researchers from the National Institute of Standards and Technology, Gaithersburg, MD, along with other institutions, has developed a toolset to allow them to explore the interior of microscopic, multi-layered batteries. This allows them insight into the batteries’ performance without destroying them—resulting in both a useful probe for scientists and a potential power source for micromachines.
3D Printer That Could Build a Home in 24 Hours Wins Global Design Competition

New York, NY – Contour Crafting, a computerized construction method that rapidly 3D prints large-scale structures directly from architectural CAD models, has been awarded the grand prize of $20,000 in the 2014 "Create the Future" Design Contest. Contour Crafting automates the construction of whole structures and radically reduces the time and cost of construction. The large-scale 3D printing technology is revolutionary to the construction industry and could lead to affordable building of high-quality, low-income housing; the rapid construction of emergency shelters; and on-demand housing in response to disasters. NASA is looking at the technology for building moon and Mars bases. Behrokh Khoshnevis, a professor at University of Southern California, who invented Contour Crafting, views this invention as a proven concept. “Bringing 3D printing to construction is bringing a concept to a proven application. For many years, building has been done in layers – concrete foundation blocks, brick laying, structural framing, etc.” “I am very happy to receive this award and find it to be very timely as I am in the process of fund raising and I think this recognition will help me greatly in furthering the project,” said Khoshnevis. Contour Crafting was among the 1,074 new product ideas submitted in the 12th annual design contest, which was established in 2002 to recognize and reward engineering innovations that benefit humanity, the environment, and the economy. This year’s design contest was co-sponsored by COMSOL (www.comsol.com) and Mouser Electronics (www.mouser.com). Analog Devices and Intel were supporting sponsors. In addition to the grand prize of $20,000, first-place winners (of Hewlett-Packard workstations) were named in seven categories: *Aerospace & Defense: The Polariton Interferometer - a Novel Inertial Navigation System Frederick Moxley A stealth navigation system that provides precise course-plotting while operating independently from GPS. *Automotive/Transportation: Continuously Variable Displacement Engine Steve Arnold A continuously variable stroke engine that operates at 30% better fuel efficiency than conventional thick stroke engine designs. *Consumer Products: NanoFab Lab...in a Box! Jonathan Moritz (Team Leader) An educational kit that brings nanomanufacturing out of the cleanroom and into the classroom. *Electronics: A Paradigm Shift for SMT Electronics Jim Hester (Team Leader) Micro-coil springs that provide flexible electrical interconnections for integrated circuit packages, preventing connection breaks due to heat and vibration. *Machinery/Automation/Robotics  – sponsored by Maplesoft: Automatic Eye Finder & Tracking System Rikki Razdan (Team Leader) Real-time point-of-gaze eye tracking system that allows users to control computer input through "Look and Click" applications.  *Medical: HemeChip for Early Diagnosis of Sickle Cell Disease Yunus Alapan (Team Leader) A biochip that can rapidly, easily, and conclusively identify the hemoglobin type in blood to diagnose Sickle Cell Disease in newborns. *Sustainable Technologies: Ecovent Systems - Making Every Room the Right Temperature Dipul Patel (Team Leader) A system of wireless vents and sensors that makes any forced air heating and cooling system smarter by directing conditioned air where it’s needed most. Finalists were selected by senior editors at Tech Briefs Media Group and judged by an independent panel of design engineers. Visitors to the contest Web site could vote on entries, with the 10 most popular designs awarded a Sphero mobile game system by Orbotix.

Connecting the World with Tiny Radios
Posted in News, Board-Level Electronics, Electronic Components, Electronics, Power Management, Power Supplies, Diagnostics, Patient Monitoring on Wednesday, 17 September 2014
A Stanford University engineering team has built a radio the size of an ant that requires no batteries. The device gathers all the power it needs from the same electromagnetic waves that carry signals to its receiving antenna. Designed to compute, execute, and relay commands, the tiny wireless chip costs pennies to manufacture, making it cheap enough, they say, to become the missing link between the Internet and the connected smart gadgets envisioned in the “Internet of Things.”
First Ultra-Flexible Graphene-Based Display Produced

A team of scientists in a collaboration between the Cambridge Graphene Centre at the University of Cambridge, UK, and Plastic Logic Ltd., also in Cambridge, have created a prototype of a flexible display incorporating graphene in its pixels’ electronics, marking the first time that graphene has been used in a transistor-based flexible device.
Nano-Measurements Using Optical Microscope Technique
Posted in News, Electronic Components, Electronics, Measuring Instruments on Tuesday, 02 September 2014
New research has confirmed that a technique developed previously at the National Institute of Standards and Technology (NIST) Gaithersburg, MD, can enable optical microscopes to measure the 3D shape of objects at nanometer-scale resolution—far below the normal resolution limit for optical microscopy. The results could make the technique a useful quality control tool in the manufacture of nanoscale devices such as next-generation microchips.
New Circuits Can Function at Temperatures Above 650°F
Posted in News, Board-Level Electronics, Electronic Components, Electronics, Power Management, Automotive on Monday, 11 August 2014
Engineering researchers at the University of Arkansas have designed integrated circuits that can survive at temperatures greater than 350 degrees Celsius — or roughly 660 degrees Fahrenheit. Their work, funded by the National Science Foundation, will improve the functioning of processors, drivers, controllers and other analog and digital circuits used in power electronics, automobiles and aerospace equipment, all of which must perform at high and often extreme temperatures.
Engineers Hope to Create Electronics That Stretch at the Molecular Level
