IEC 60601-1-2 Edition 4: New Requirements for Medical EMC

Plan now to ensure your medical devices comply with new IEC 60601-1-2 EMC 4th Edition standard requirements by the December 2018 effective date. Since the development cycle can be 2-3 years, it is important to understand the new standard now when designing medical devices.

New Stamping Technique Enables Printable Electronics

The next time you place your coffee order, imagine slapping onto your to-go cup a sticker that acts as an electronic decal, letting you know the precise temperature of your coffee. Engineers at MIT have invented a fast, precise printing process that may make such electronic surfaces an inexpensive reality. The stamp is made from forests of carbon nanotubes and can print electronic inks onto rigid and flexible surfaces. The stamping process should be able to print transistors small enough to control individual pixels in high-resolution displays and touchscreens. It could also offer a relatively cheap, fast way to manufacture electronic surfaces for as-yet-unknown applications.

Is nine hours a day too much "screen time?"

This week's Question: A recent study from Common Sense Media found that parents spend more than nine hours (9:22) a day with screen media, with the vast majority of that time being spent with personal screen media (7:43) and only a little more than 90 minutes devoted to work screen media. Most parents surveyed (78 percent) believe they are good media-use role models for their kids.

What do you think? Is nine hours a day too much "screen time?"

Edge-Connect SBC

ADL Embedded Solutions Inc. (San Diego, CA) has announced its compact ADLE3800SEC SBC with Edge-Connect. This ultra-compact 75mm x 75mm form factor is a full-featured, standalone SBC for rugged, embedded applications. The ADLE3800SEC is ideal for rugged, extended temperature intelligent systems with stringent size, weight, and power (SWAP) requirements. It boasts a wide thermal junction temperature (Tj) range (-40°C to +85°C), wide input voltage (20-30 VDC), DisplayPort, USB2.0, USB3.0 and two GLAN ports with support for DirectX 11, Open GL 4.0, and full HD video playback. The Edge-Connect architecture allows for added I/O expansion and connectors in a variety of baseboard/breakout board configurations (flat, vertical, odd-shapes, etc.).

Computer chips in development at the University of Wisconsin–Madison could make future computers more efficient and powerful by combining tasks usually kept separate by design. Jing Li, an assistant professor of electrical and computer engineering at UW–Madison, is creating computer chips that can be configured to perform complex calculations and store massive amounts of information within the same integrated unit — and communicate efficiently with other chips. She calls them “liquid silicon.”

A new, ultrathin film that is both transparent and highly conductive to electric current has been produced by a cheap and simple method devised by an international team of nanomaterials researchers from the University of Illinois at Chicago and Korea University. The film is also bendable and stretchable, offering potential applications in roll-up touchscreen displays, wearable electronics, flexible solar cells and electronic skin.

SWaP-C and Why Your Component Partner Matters

The military is continually pushing to decrease the size, weight, power and cost (SWaP-C) of its electronics, particularly for items carried by the troops. To meet these goals, everyone involved in designing and manufacturing the device needs to work together closely to ensure maximum efficiency of every component. This makes choosing the right partner crucial. Our white paper explores why SWaP-C is so important and includes information on:

For more than a decade, engineers have been eyeing the finish line in the race to shrink the size of components in integrated circuits. They knew that the laws of physics had set a 5-nanometer threshold on the size of transistor gates among conventional semiconductors, about one-quarter the size of high-end 20-nanometer-gate transistors now on the market. But some laws are made to be broken, or at least challenged.
