The rising interest in the terahertz band of frequency and the recent research in this area have motivated the organizers to foster an IMS workshop to address the state-of-the-art of this new technology. The goal of the proposed workshop is to addresses the recent research progress in terahertz systems, passive and active devices, sources, and imaging algorithms.
Imagine being able to use electricity to power your car — even if it's not an electric vehicle. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have for the first time demonstrated a method for converting carbon dioxide into liquid fuel isobutanol using electricity. Today, electrical energy generated by various methods is still difficult to store efficiently.
American researchers have created a robotic jellyfish, named Robojelly, which not only exhibits characteristics ideal to use in underwater search and rescue operations, but could, theoretically at least, never run out of energy thanks to it being fuelled by hydrogen. Constructed from a set of smart materials, which have the ability to change shape or size as a result of a stimulus, and carbon nanotubes, Robojelly is able to mimic the natural movements of a jellyfish when placed in a water tank and is powered by chemical reactions taking place on its surface.
A North Carolina State University researcher has developed a more efficient, less expensive way of cooling electronic devices – particularly devices that generate a lot of heat, such as lasers and power devices. The technique uses a “heat spreader” made of a copper-graphene composite, which is attached to the electronic device using an indium-graphene interface film “Both the copper-graphene and indium-graphene have higher thermal conductivity, allowing the device to cool efficiently,” says Dr.
Scientists and engineers at the University of Wisconsin-Milwaukee (UWM) have discovered an entirely new carbon-based material that is synthesized from the “wonder kid” of the carbon family, graphene. The discovery, which the researchers are calling “graphene monoxide (GMO),” pushes carbon materials closer to ushering in next-generation electronics.
To improve reliability and performance in telecommunication equipment, W. L. Gore & Associates has advanced its portfolio of products and services that enable the industry to remain connected and protected. In addition to introducing its new business unit that focuses on mobile devices, Gore is displaying new venting products, cooling filters, and testing methods to enable manufacturers and suppliers of wireless headsets, small cell devices, base stations and other telecommunication infrastructure to improve product performance for their customers.
Not a week goes by without reports on security gaps, data theft or hacker attacks. Both businesses and private users are becoming increasingly uneasy. However, when it comes to technologies like cloud computing, trust and security are essential if we intend to use data and applications that are flexible, cost-effective and above all, mobile.

Preventing Failure: New Magnetic Testing Technique Helps Ensure Reliability of Microelectronic Devices, PV Cells and MEMS ApplicationsApril 16, 2012 6:03 am | Comments
Taking advantage of the force generated by magnetic repulsion, researchers have developed a new technique for measuring the adhesion strength between thin films of materials used in microelectronic devices, photovoltaic cells and microelectromechanical systems (MEMS). The fixtureless and noncontact technique, known as the magnetically actuated peel test (MAPT), could help ensure the long-term reliability of electronic devices, and assist designers in improving resistance to thermal and mechanical stresses.
How hydrogen--the most abundant element in the cosmos--responds to extremes of pressure and temperature is one of the major challenges in modern physical science. Moreover, knowledge gleaned from experiments using hydrogen as a testing ground on the nature of chemical bonding can fundamentally expand our understanding of matter.
Computer chips have stopped getting faster. In order to keep increasing chips’ computational power at the rate to which we’ve grown accustomed, chipmakers are instead giving them additional “cores,” or processing units.

Cell phones and flashlights operate by battery without trouble. Yet because of the limited lifespan, battery power is not a feasible option for many applications in the fi elds of medicine or test engineering, such as implants or probes. Researchers have now developed a process that supplies these systems with power and without the power cord.
All medical device manufacturers must comply with the updated IEC 60601-1 Standard, or the 3rd Edition, establishing new requirements for the safety and effectiveness of medical equipment. The standard will take effect in June 2012 in Europe and Canada and in June 2013 in the United States. Failure to implement the requirement can result in delaying the product to market and lost revenue.
KIT digital unveiled its next generation social TV solution, the KIT Social Program Guide (KIT SPG), at NAB 2012 (booth SU8505). The KIT SPG integrates users' social networks with their service provider's electronic program guide, allowing viewers to enjoy a full range of social TV functions, as well as change the channel, through a single intuitive interface.
The International Electrotechnical Commission (IEC) has ratified a new standard – ISO/IEC 14543-3-10 – for wireless applications with ultra-low power consumption. It is the first and only wireless standard that is also optimized for energy harvesting solutions and, therefore, for EnOcean's self-powered wireless technology.
