New Electrical Conductor Outperforms Graphene

 

A new superconductor made from tin atoms is poised to overtake graphene by becoming the world’s first material to conduct electricity with 100 percent efficiency at the high operating temperatures used by computer chips. Known as “stanene,” the material was discovered by a team of theoretical physicists led by researchers from the U.S. Department of Energy’s (DOE) SLAC … [Read more...]

Common-Mode Chokes for CAN and FlexRay Bus Systems

 

Electronic component manufacturer TDK Corporation has released the new ACT1210 series of common-mode chokes for both CAN and FlexRay bus systems. With compact dimensions of just 3.2 mm x 2.5 mm x 2.4 mm and a footprint approximately 45 percent smaller than that of existing components, the new ACT1210 series of common-mode chokes are the world’s smallest, the company said.  The … [Read more...]

Quadriplegics Drive Wheelchairs with Magnetic Tongue Piercing

 

In a move that promises to improve the lives of millions of people around the world who are paralyzed from the neck down, researchers at the Georgia Institute of Technology have developed a unique wireless device that allows users to control a specially-designed wheelchair with their mouths. “The Tongue Drive System is a novel technology that empowers people with disabilities … [Read more...]

Combining Antennas and Solar Cells for Greater Efficiency

 

Researchers at the École polytechnique fédérale de Lausanne (EPFL) in Switzerland have combined antennas and solar cells in a breakthrough step towards the development of smaller and more lightweight satellites and autonomous antenna systems. Traditionally, telecommunication antennas and solar cells have been built separately to avoid interference, the researchers said. This … [Read more...]

EMI shielding specialist Central Coating Co. Inc. has released two new materials for EMI shielding applications. The first material is an electrically-conductive, one-component, nickel-filled acrylic coating ideal for application on plastics to provide modest EMI shielding and anti-static protection for electronic enclosures and assemblies where abrasion resistance and coating … [Read more...]

Ultra-Low-Height Board-Level EMI Shield for Compact Electronics

 

EMI solutions provider Laird Technologies has released a new ultra-low-height two-piece board-level EMI shield for compact electronics with small space requirements. The new board-level shield incorporates a frame with a patent-pending drawn latch design that allows for simplified tooling and tighter tolerances. The design accommodates assembly heights as low as 1 mm. “This … [Read more...]

Power Grid, Mains Filtering and Power Line Communications… A Root Cause for Incompatibilities?

 

This article has been translated from Dutch to English. It can be found in its original language in the 2014 Europe EMC Guide. Mart Coenen, Owner, EMCMCC, the Netherlands The power grid is intentionally meant to distribute electrical energy at the mains frequency, as produced by the electricity generating plants, towards the end-users. The three-phase low-voltage distribution … [Read more...]

New Tool Detects and Traces Electromagnetic Attacks

 

With the ability to interfere with or damage electronic devices, electromagnetic pulses (EMP) are considered one of the most dangerous threats facing modern electronic systems and infrastructure. Man-made EMPs in particular can be used to deliberately disable power grids and defense and security systems without leaving any indication as to the specific nature or origin of the … [Read more...]

Assemblies Provide EMI/RFI Protection for High-Powered Switching and Rugged Applications

 

Interconnect solutions provider Molex Inc. has released its new Woodhead MAX-LOC Plus Shielded Cord-Grip assemblies featuring a nickel-plated aluminum housing and shielding ring for EMI/RFI protection. According to the company, the assemblies enable original equipment manufacturers (OEMs) and end-users to connect high-power electrical currents directly to an application with … [Read more...]

Edge Guide Clip-On Strip Reduces Design Costs in PCB Grounding & Shielding Applications

 

EMC solutions provider Laird Technologies has announced the release of its new Fingerstock product, the Edge Guide Clip-On Strip. Available in custom lengths, the new product is designed to help reduce installation and labor costs in applications where PCBs need to be grounded and/or shielded. For example, says the company, a 10 cm or eight finger strip could reduce … [Read more...]
