November 16, 2009[Electronic Design Products] 2D Communications Sheet Challenges 3D Trends
Last month, Teijin Fibers unveiled a 2D communication sheet that it says provides simple, secure wireless local-area network (WLAN) connections. According to the company, communications are rapidly migrating from 1D cable to 3D wireless topologies, while it forges development in the 2D domain. With the growing trend toward 3D communications, this 2D approach may seem like a step backward. But Teijin Fibers, which primarily designs and creates unique...
November 16, 2009[Technology Report] What's New In ESD Protection Devices
Obviously, electrostatic discharge (ESD) is one of many critical considerations in almost every design project. Equally obvious is the fact that there is no shortage of solutions to keep ESD at bay. Maxim Integrated Products describes its MAX4895E as the industry’s smallest VGA-port protector (Fig. 1). In addition to ESD protection on all seven of its video outputs, the 3- by 3-mm, 16-pin thin quad...
October 22, 2009[TechView: Components & Test] Low-Power Actuator Suits In-Vivo Biomedical Apps
Fabricated using silicon-oninsulator micromachining techniques, Imec’s latest actuator operates with ultralow power. It’s also watertight, making it viable for use in in-vivo biomedical devices and other applications that need to combine a long autonomy with small batteries (see the figure). The prototype integrates a micro needle, which is steerable by the actuator, and combines a...
April 23, 2009[Electronic Design Products] University Researchers Roll Out First Flexible Display With Touchscreen
Partnering with E Ink Corp. and DuPont Teijin Films, researchers at Arizona State University’s Flexible Display Center (FDC) have created what they are dubbing the world’s first active-matrix display on a flexible substrate with a touchscreen (Fig. 1). Also heralded as a revolutionary breakthrough, the glass-free display is reportedly the first of its kind to enable real-time user input. ...
March 26, 2009[Electronic Design Products] Technology Shrinks PCB Motors While Boosting Accuracy
The march for miniaturization never stops as evidenced by portable products the size of a credit card that outperform some laptop and even desktop computers. Probably one of the most challenging markets in this quest for tinier gadgets is motors and motion control. Though still daunting, shrinking a semiconductor should be less of a burden because there are no moving parts to consider. But squeezing a motor and related control circuitry onto the head of a pin is...
February 26, 2009[Electronic Design Products] Mature Display Technology Still Viable In Advancing Markets
When we think of displays these days, the first technologies that come to mind are LCDs, LEDs and organic LEDs (OLEDs), and touchscreens. These components, though not new, proliferate and evolve because of a number of factors. Constant research and development in the electrical, mechanical, and chemical/materials disciplines uncovers ways to make these displays cheaper, more functional and energy efficient, and easier to integrate into new...
January 29, 2009[Electronic Design Products] BSI Technology Takes A Major Leap Forward
Since their efforts were first reported in June 2008, CMOS image sensor specialists at OmniVision have been very busy perfecting their backside illumination technology (see â??BSI Technology Flips Digital Imaging Upside Downâ?? at www.electronicdesign.com, ED Online 19160). Teaming with semiconductor...
January 15, 2009[Technology Report] Touch Sensors Press For Low Costs, Streamlined Design
In terms of overall integration, touch sensors and their related components are probably the most seamless technologies. From automated teller machines (ATMs), cell phones, and video games to test-and-measurement and medical equipment, touch interfaces can be found nearly everywhere. And unless they’re confusing or inoperable, they’re taken for granted by most users. In a brief period, touchscreens have evolved beyond the simple, single-button entry format. State-of-the-art...
January 15, 2009[Technology Report] Power Sources Generate Green By Going Greener
From ever-shrinking dc-dc converters to brute-force industrial and benchtop power supplies, one of the top priorities for power designers has always been efficiency—eliminating the power losses when converting power from one form or level to another. For instance, not so long ago, we saw the shift from linear regulators and 50/60-Hz power transformers to high-frequency switching power supplies. Today, the buzzword for efficiency is “green.” Emerging power sources flying under...
January 15, 2009[Technology Report] Connector And Cable Makers Can’t Stand Pat
The connector market is huge, diversified, and convergent, from consumer to commercial through medical to military and aerospace, all with equally daunting and diverse opportunities for innovation and creativity. In fact, “all markets are ripe for innovation in interconnects,” says Rob Rix, vice president of Industry Marketing, Communication & Industrial Solutions at Tyco Electronics. In the anatomy of all things electronic, connectors and cables are the...
December 11, 2008[EEPN In Electronic Design] Capacitive Sensors Squeeze Versatile Touch Into Tight Quarters
Probably the greatest demand for highly featureridden touchscreens comes from the portable market, with the iPhone and similar communications products as ripe examples. But while it’s one thing to integrate a simple touchscreen accepting single-touch input to control the basic functions of a device, simple touchscreens are few and far between these days. Give or take a few millimeters, the typical area for input on a cell phone is about the size of a credit...

December 1, 2008[Technology Report] Diverse Component Trio Represents This Year's Best
The components market always seems to be in a state of accommodation, creating products to support every other sector’s designs. Whether it’s a power source that fits an oddly shaped printed-circuit board (PCB) or a motor that can deliver massive torque levels in a space the width of a finger, component makers innovate for innovators. Over the past year, for example, OmniVision gave digital-camera designers a leg up in their work with its BSI CMOS...
