Might it one day be possible to transmit electricity from an offshore wind turbine to land-based users without any loss of current? Materials known as "high temperature" superconductors (even though they must be maintained at -140°C!), which can conduct electricity without any losses, were supposed to make this dream a reality.
An interdisciplinary team of researchers at Vanderbilt University have developed a way to combine the photosynthetic protein that converts light into electrochemical energy in spinach with silicon, the material used in solar cells, in a fashion that produces substantially more electrical current than has been reported by previous "biohybrid" solar cells.
Plastic optical fibres, laid on the underlay of a carpet, can bend when anyone treads on it and map, in real-time, their walking patterns. Tiny electronics at the edges act as sensors and relay signals to a computer. These signals can then be analysed to show the image of the footprint and identify gradual changes in walking behaviour or a sudden incident such as a fall or trip.
Stanford electrical engineers overturn existing models to demonstrate the feasibility of a millimeter-sized, wirelessly powered cardiac device A team of engineers at Stanford has demonstrated the feasibility of a super-small, implantable cardiac device that gets its power not from batteries, but from radio waves transmitted from outside the body.
A bad weather front is fast approaching and a cloudburst is imminent. If you happen to be away from home, but have left a window open, either deliberately or because you forgot to check one room, you may be in for a wet surprise when you come home. However, it does not have to be like that: Thanks to a new sensor system, such situations can now be avoided.
For years, professional football players have been forced to lug around hefty playbooks. But the three-ring binders — stuffed with dozens of offensive plays and defensive schemes — are going the way of leather football helmets. The Seattle Seahawks are now converting plays to PDFs and uploading to tablets, with the players using the devices not only to study plays but also to watch video highlights of games and practices.
New Yorkers have long adopted their own techniques in the fine art of hailing a taxicab, a theatrical, frustrating, competitive ritual of the city. There is the high-pitched whistle, the two-handed gesticulation, the rapid snapping of fingers. Many favor the classic wave — an open palm raised high, stretching into coming traffic.
Rogers Corporation will be displaying three of their leading high-performance circuit materials for mobile and fixed-site antennas at the upcoming Mobile Antenna Systems 2012 conference and exhibition. This key event for designers and specifiers of antennas for a wide range of fixed and mobile applications is scheduled for September 18-19, 2012 at the Hyatt Denver Tech Center (Denver, CO).
This is what we talk about when we talk about Disrupt. uBeam , a small startup founded by Meredith Perry , a 22-year-old new graduate from the University of Pennsylvania, has taken on $750,000 in seed funding to build out its technology for wirelessly charging electronic devices. uBeam’s investors include Founders Fund’s angel investing arm , Andreessen Horowitz , Crunchfund , and a number of individual angel investors including Google’s Marissa Mayer and Zappos co-founder Tony Hsieh , uBeam’s Meredith Perry told TechCrunch today in a phone interview.

At the IFA tech show here, or at any tech show, it’s not hard to find wireless speakers that pair with smartphones and tablets. But audio company Creative is being more creative with a speaker that can function on its own for basic stereo or link wirelessly with additional speakers to form a surround-sound system.
Withings has introduced a new set of wireless bathroom scales to spare us sedentary geeks the effort of recording our weekly weigh-ins . The updated set includes Position Control technology, which we assume means it tells you to stand up straight and suck your belly in while it's sending your details to the internet .
The reality of our multi-screen world is that consumers are increasingly turning to different devices throughout the day to accomplish tasks. A user might rely on a smartphone to dash off a quick text message or to scan a product in store, then use a tablet to plan trips at home and then turn to a PC to do more heavy research.
