There are a variety of systems and applications that could benefit from energy harvesting (EH). Energy harvesting refers to the technology by which ambient sources of energy such as light, thermal gradient, and vibration can be harvested and stored then applied later for doing useful work.
Summit Microelectronics has expanded its fourth-generation family of programmable Li-Ion battery charger integrated circuits (ICs) with the introduction of two new products. The SMB346 and SMB347 deliver up to 2.5A charge/system current...
At today’s 2011 IEEE International Electron Devices Meeting (IEDM) Imec and Holst Centre announced that they have made a micromachined harvester for vibration energy with a record output power of 489µW.
An upcoming cycle of stormy solar activity risks causing damage to electrical transformers and threatening vulnerable energy infrastructure around the globe, a report by an insurance group says.
Heliatek GmbH has set a new world record for organic solar cells after Fraunhofer ISE CalLab certified a cell efficiency of 9.8% for a 1.1 cm² tandem cell manufactured with a low temperature deposition process. This new record makes the third time in a row that Heliatek has set a world record for efficiency in the field of organic photovoltaic and demonstrates its continuous technology leadership in organic solar.
The threat of cyberattacks on the U.S. power grid should be dealt with by a single federal agency, not the welter of groups now charged with the electric system's security, researchers at the Massachusetts Institute of Technology reported on Monday.
Once you’ve selected the right low power microcontroller, how important is your application code in achieving energy saving and efficiency goals? And how do you go about optimizing it for ultra low power operation? Answering such questions has always been difficult, since correlating current consumption with software code has traditionally been a somewhat inexact and cumbersome task.
Clean, uninterrupted power is the goal of every facility, data center manager and executive overseeing continuous business operations and processes. With brownouts and blackouts occurring more often than ever, businesses need critical power protection.
Imec together with its silicon photovoltaic industrial affiliation program partners Schott Solar, Total, Photovoltech, GDF-SUEZ, Solland Solar, Kaneka and Dow Corning, have demonstrated an excellent conversion efficiency of 23.3% on interdigitated back-contact (IBC) silicon solar cells.
When you evaluate alternate-energy sources look at your entire system to find ways to reduce power use.
The Keesler Hospital's operating room is once again "going green." In 2004, Capt. Wendy Wilkins, an 81st Surgical Operations Squadron operating room nurse, began reprocessing the Flowtron compression hoses used in the operating rooms.
ROAL Electronics announced a new family of very efficient and compact Medical power supplies. The MDP400 series has several package options including open frame, U-chassis, enclosed chassis, and environmentally sealed IP65 rated versions.
The sun's abundant energy, if harvested in space, could provide a cost-effective way to meet global power needs in as little as 30 years with seed money from governments, according to a study by an international scientific group.
Can some one please tell me the point of making our electrical grid more hackable than it already is? And please. Don't tell me about "security". Security is only a delaying tactic. Some one who wants to can figure out how to defeat it.
The market for PV manufacturing equipment will more than halve in 2012 according to the latest quarterly-updated report from IMS Research. Significant decreases in the “new” manufacturing capacity required and limited demand for upgrade...
Illuminating an LED at high brightness requires driving it with as high a current as allowed by the manufacturer, but the life expectancy of LEDs is heavily dependent on operating temperature. An increase of only 10°C can cut its useful life in half.
GAIA Converter has released a new family of high input voltage DC/DC Converters targeting Avionic, Aerospace, Military and Missile applications. The MGDS-75-S series have an input voltage range of 155-480V...
Following the success with Nissan LEAF, ”European Car of the Year 2011”, the Renault Nissan Alliance has selected Telenor Connexion as its European supplier of connectivity for Renault’s new electric and internal combustion car models as well.
Future Energy Solutions is pleased to announce the launch of the first comprehensive energy specific website, connecting the rapidly growing alternative energy market with innovative electronics component solutions – www.FutureEnergySolutions.com.
The IEEE Communications Society (ComSoc) recently held its first fully-virtual, online event with professionals worldwide participating in 12 separate sessions dedicated to the latest advances in energy-efficient communications and green technologies.
HP announced a new industry program comprising a new server development platform, customer discovery lab and partner ecosystem to help customers significantly reduce complexity, energy use and costs.
