I hate to shop. I especially dislike it during the holidays. But if any store at the mall had a sale on these new e-textiles, I might consider going. This electronic cloth, interwoven with microelectronics, serves as a large detection array that pinpoints sources of faint sounds. Co-investigators Robert Parker and Mark Jones at the University of Southern California School of Engineering's Information Sciences Institute in Los Angeles, CA, embedded arrays of small, standalone detectors into fabrics that communicate with each other by wires. Existing prototype fabrics have discrete electronics attached after the normal weaving process, says Parker. But the goal is to eventually produce individual yarns that provide an electronic function such as a battery power source or a transistor array; a sensor of environmental conditions such as temperature or airborne toxins; or an actuator such as a synthetic muscle. In the immediate future, Parker expects these fabrics to be sewn into parachutes or tents for the military where they could be used for surveillance missions or to detect distant vehicles moving on battlefields. "These yarns are conceived to be very thin and flexible and able to be woven into the cloth on a loom in a standard high-volume cloth manufacturing process," says Parker. The type of fabric chosen would be determined by its final use and could vary from cottons for shirts to heavy canvas or Kevlar for heavy-duty military applications. "Although early work focuses on acoustic sensing, think of future wearable fabrics with integrated cell phones, navigation systems, or personal warning systems," says Parker. "Think of your shirt or slacks 'interacting' with the environment as you pass through it. Think of walking into a mall and your shirt tells you where you can get that special gift item that has been on your 'must get' list for months." Now that may be enough to even get me into the malls!

Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
