Hospital-Grade Standards for Power Cords and Other Power System Components for Global Markets
Posted in Features, Electronic Components, Power Management, Power Supplies, FDA Compliance/Regulatory Affairs on Wednesday, 31 December 2014
While a number of countries have standards in regards to overall medical equipment, a few countries have related component requirements (e.g. plugs and cords). For the countries that do have hospital-grade or medical application standards on components, it is important to know what the requirements are so as to comply with that country or region’s rules.

Researchers Develop a Way to Control Material with Voltage
Posted in News, Batteries, Board-Level Electronics, Electronic Components, Power Management, Metals on Wednesday, 03 December 2014
A new way of switching the magnetic properties of a material using just a small applied voltage, developed by researchers at MIT and collaborators elsewhere, could signal the beginning of a new family of materials with a variety of switchable properties. The technique could ultimately be used to control properties other than magnetism, including reflectivity or thermal conductivity. The first application of the new finding is likely to be a new kind of memory chip that requires no power to maintain data once it’s written, drastically lowering its overall power needs. This could be especially useful for mobile devices, where battery life is often a major limitation.

Garnet Ceramics Could Be the Key to High-Energy Lithium Batteries
Posted in News, Batteries, Electronic Components, Power Management, Energy Efficiency, Ceramics on Wednesday, 03 December 2014
Scientists at the Department of Energy’s Oak Ridge National Laboratory have discovered exceptional properties in a garnet material that could enable development of higher-energy battery designs. The ORNL-led team used scanning transmission electron microscopy to take an atomic-level look at a cubic garnet material called LLZO. The researchers found the material to be highly stable in a range of aqueous environments, making the compound a promising component in new battery configurations.

Technique Generates Electricity from Mechanical Vibrations
Posted in News, Power Management, Energy Harvesting on Thursday, 20 November 2014
Research scientists at VTT Technical Research Centre of Finland have demonstrated a new technique for generating electrical energy. The method can be used in harvesting energy from mechanical vibrations of the environment and converting it into electricity. Energy harvesters are needed in wireless self-powered sensors and medical implants, where they could ultimately replace batteries. The technology could be introduced on an industrial scale within three to six years.

New System Could Prolong Power in Mobile Devices
Posted in News, Electronic Components, PCs/Portable Computers, Power Management on Sunday, 26 October 2014
Researchers from The University of Texas at Dallas have created technology that could be the first step toward wearable computers with self-contained power sources or, more immediately, a smartphone that doesn’t die after a few hours of heavy use. The technology taps into the power of a single electron to control energy consumption inside transistors, which are at the core of most modern electronic systems.

Improved Fuel Cells Could Replace Phone and Laptop Batteries
Posted in News, Power Management, Energy Efficiency, Energy Storage on Sunday, 26 October 2014
Fuel cells could replace batteries in mobile phones and laptop computers, and the UPV/EHU-University of the Basque Country is looking at ways of enhancing their efficiency. Researchers are designing new ways of obtaining energy in a cleaner, safer, and more affordable way. Fuel cells are totally appropriate systems for substituting the batteries of such devices. They turn the energy resulting from the combining of hydrogen and oxygen into electrical power, with water vapor being the only waste product.
