This sensor knows if you like anime a little too much
At some point in life, you may have wondered: would you prefer dating an anime character instead of an actual human being? If you're unsure, ROHM's here to help. At CEATEC, the component maker paired up with TECHMAC to show off a dating game featuring a "Tokimeki Sensor" -- "tokimeki" is a Japanese word for "palpitation" that's often associated with dating simulators. The player places his or her hand on a board, with the index fingers placed on an optical palpitation sensor on the back. The subject then faces a flirty anime boy or girl on the left screen for about a minute, followed by its human counterpart on the right, and then the game will determine whether you're into 2D romance instead of 3D. We didn't dare to face the truth, because you know, the heart never lies, but our friend Tim Stevens wasn't so sure about this machine's accuracy.
This paper origami bird actually flies
Origami and technology go together pretty well. Lightweight, efficient structures... and animal shapes. But there's nothing more "origami" than the humble paper crane. Now, courtesy of a small, light, power-efficient microcomputer from Rohm (a Japanese company: don't let the name fool you), the crane can fly. Better still, it's remote-controlled and can even keep itself afloat for around five minutes, according to the spokesperson. It's almost the most Japanese thing here at this year's CEATEC. Almost.
Rohm showcases colorful solid hydrogen-source fuel cell chargers at CEATEC
You know what makes a fuel cell charger in your pocket a little less frightening? Colors! CEATEC mainstay Rohm has arrived back in Japan with a new set of hydrogen-source fuel cell chargers, with the latest prototype lot boasting a litany of new hues that may very well match up with that iPhone 5c you're (presumably) picking up soon. The actual technology used within hasn't changed from last year, but the company is evidently considering the release of such portable chargers for those who'd prefer something a bit less drab. We're told that a fully-fueled pack can keep the average smartphone alive for twice as long as it would otherwise last, but as has become the norm at this show, there's nary a hint of a price / release date.

Rohm 5Wh hydrogen fuel cells power up smartphones, ready for the trash after one charge
Rohm's hydrogen fuel cells are meant to power smartphones and other mobile devices, but unlike other juicing-up solutions, the cells are only good for one charge. Rohm says disposable fuel cells can be made smaller and lighter than their multi-use counterparts, and as the only byproduct is hydrogen, the company is touting the cells' eco-friendliness. The system generates electricity by using hydrogen that's created by the reaction of a metal material and water. While the device we saw here at CEATEC is a prototype, Rohm may offer its recharging system as both a smartphone case and a USB-attachable juicepack. Each offers 5Wh and can fully charge a handset once. There's also a 200W power generator, which certainly stretches the meaning of portable but can keep a laptop, LCD TV and a peripheral or two going for three to four hours. Rohm says its fuel cells will see a commercial release some time in 2013; for now you can get a sneak peek in our hands-on gallery below. Zach Honig contributed to this report.
Terahertz wireless chip could deliver 30Gbps of bandwidth, stream uncompressed 4K video
Usually, when we start talking terahertz, it means one thing: lasers! But not today, friends. Today, we're talking something with a little less flash and a little more potential for everyday use. ROHM, a Japanese electronics component manufacturer, has developed a chip measuring just 1.5mm by 3mm that can transmit data at up to 1.5Gbps using those precious terahertz radio waves. That's both significantly smaller and faster than existing terahertz wireless experiments and the research teams at ROHM and Osaka University (who are collaborating on the project) believe they can scale the tech up to 30Gbps -- enough bandwidth to stream HD video to every room in your home, provided you don't live in a 200 room mansion. Perhaps most exciting though, producing these chips costs only a few hundred Yen, while earlier versions saw prices hovering at around several thousand.

Rohm Wireless Power Transmission system hands-on (video)
Wireless power demos abound at CEATEC, and Rohm Semiconductor had their own variant on hand with a complete mix of direct-draw gadgets, along with the omnipresent charging iPhone 4 (or was it a 4S?). Like Murata's prototype, the Rohm flavor uses square electrodes instead of the coils that you'll find in traditional wireless power solutions, like Qi. But unlike that seemingly identical solution from Murata, this version supports much greater power efficiency -- something in the 92 to 93 percent range (compared to the competing pad's 70-percent efficiency rating). That means that the prototype that we're looking at here loses just seven to eight percent of power during transmission -- which is still unacceptably high, mind you, but far more tolerable. Rohm's Wireless Power Transmission system also allows you to charge or power devices by placing them anywhere on the pad, rather than directly over charging positions, and it supports much greater transmission, with one prototype outputting up to 100 watts. Since power efficiency isn't something we could verify visually, what we could see at the company's demo did appear to work quite well. Powering a gadget is as simple as dropping it on the pad. Well, resting it gently -- this is a prototype we're talking about, after all. The 50-watt pad was able to power a fan, LED light, and a couple of charging smartphones without issue. The light and fan jumped to full power as soon as they made contact. A second pad got the juices flowing to a large OLED light panel, which was plenty bright when positioned on its own pad, but glowed quite dim when joining other devices. There weren't any charging laptops on hand, like we saw over at Murata, but with power output at 50 and 100 watts, either pad could theoretically support it. Like many of the prototypes we've seen at CEATEC, there aren't any plans to actually bring the system to market, but the technology could be used in other devices. We go hands-on after the break.%Gallery-135773%
Rohm and Lumiotec create $450 OLED Hanger lamp, we go hands-on (video)
Four hundred and fifty dollars. Made out to Lumiotec, please. Really, that's all you need to know -- this tiny purposeless OLED lamp costs nearly half a grand. But hot damn does it look good. If you have the cash and don't mind shelling it over, Lumiotec's OLED Hanger lamp is a mighty cool gadget to own. Until you realize that you're not really sure what to do with it. Do you hang it in a closet? Do you hang it over the door? Can you hang it anywhere at all? It is a hanger, after all. Even representatives from Rohm, which manufacturers the OLED panel used in the Hanger, were unable to explain the lamp's purpose at the company's CEATEC booth. Some variation of "use your imagination" was the final response. Well, our imagination has concluded that we'll pass on the Hanger, but we'd like a few dozen of those gorgeous OLED panels, please (we've already set aside several hundred square feet of wall space). If you're still into the Hanger, we can confirm that it's not only bright, but also very thin and very light. The panel gives off roughly the same amount of light as a 60-watt bulb, yet it consumes just 9.6 watts of power. Sadly, that doesn't mean it will eventually pay for itself in electricity cost savings, since, again, you're still paying $450 for what's essentially a (very slick) light bulb. We'd be far more impressed if the Hanger were more portable. You'll have many feet of cord to work with, but you'll still be tethered to an outlet -- there's no flat battery magic implemented here. These are available now in limited quantities, if you're ready to pull out the checkbook and sign on the dotted line. Or, if you'd rather spend that dough on a truckload of traditional fixtures, you can get your Hanger fix for free in the video after the break.%Gallery-135774%
Sony replacing handset wiring with a single copper cable
Sure, it's just boring ol' component news but you can guarantee that this advance will affect the appearance of Sony (and Sony Ericsson) products some time soon. Sony just announced the development of a "single wire interface technology" that replaces the 22 or so cables (used for power, control signals, audio, video, etc) typically found inside mobile devices (tucked away in the hinge or rotating parts) with a single copper wire cable capable of transmitting data at 940Mbps. That should translate into greater reliability while giving Sony's product teams more flexibility with their designs. Sony plans to "swiftly" implement the technology by licensing the IP to ROHM to help jointly develop the required silicon. More with less, as they say.
ROHM shows off flexible organic EL light tech in shiny bracelet form
ROHM, the Kyoto-based semiconductor company that has been promising us tiny, thin OLED lights of joy for years, has finally delivered what we've all been waiting for: a shiny, pulsating, light-up bracelet. During a construction-laden sneak peak of the CEATEC show floor, ROHM was nice enough to show us this organic EL bracelet that sports their new flexible Japanese paper-based lighting technology. This particular bracelet is powered by a wafer-thin lithium battery and is sure to go quite nicely with your little silver dress. No word on availability or pricing, but this thing is for real, and you can see as much for yourself in a fun little video after the break. %Gallery-74741%
Integrated circuits with no standby power could be in use by year's end
There's certainly no shortage of companies working to make electronics of all sorts more energy efficient, but NEC and Rohm Co now say that they're on the verge of a breakthrough that could change things in a big way, and we could possibly see it in "practical use" by the end of this year. As Tech-On! reports, both companies are hard at work on integrated circuits that consume no power at all when they're in standby mode, and turn themselves on only when power is needed. That's apparently possible by making the entire chip nonvolatile, as opposed to many current chips that only use nonvolatile merged memory. According to NEC, that'll let them "cut dissipation for digital consumer electronics in the standby mode to just a few percent of what it is now," and at no expense of convenience. While NEC isn't making any promises for the near future just yet, Rohm says that it'll begin shipping its first custom ICs in the second half of this year, and that the first products using them could start showing up by the end of 2009.
Rohm brings super-bright OLED out of the shadows, literally
Kyoto-based company Rohm impressed us at last year's CEATEC with a mega-tiny OLED display but it didn't rest on its laurels. A larger prototype exhibited this year emitted ambient light at 3,000 to 4,000cd/m² and a brief flash at 100,000cd/m² -- that's respectively 10 and 250 times the brightness of a typical LCD display. But the impressive bit was this: nothing illuminated cast a shadow. Obviously a light like that is a poor match for a haunted house or romantic restaurant, but surgeons use shadowless lamps at the operating table, so there are applications. The short shelf life of OLED materials is still a nagging disadvantage, but as Dr. Eldon Tyrell would say: "the light that burns twice as bright burns half as long, and you have burned so very, very brightly." Then again, he was talking about cybernetic killing machines, so, maybe not such a great endorsement.[Thanks, Erik]
Rohm's miniscule OLED shown at CEATEC
Rohm certainly has a thing for cranking out diminutive devices that elicit attention, and the firm chose CEATEC as the venue to demonstrate its long-awaited full-color OLED that's "smaller than a fingernail." According to a company spokesperson, the 320 x 240 resolution display measures around four- by three-millimeters, is "embedded in a prototype chip and is designed for use in a video-camera viewfinder." Notably, the unit actually requires humans to view it under a microscope in order for it to be clearly seen, and although nothing was said about a commercialization date, it was suggested that Rohm is already working up a similar version with twice the pixels.
Rohm unveils "world's smallest" LED: PicoLED
If you dig the nearly endless applications for jazzing up almost anything with light emitting diodes, you'll be thrilled to know that a Kyoto-based firm has now crafted an even smaller rendition of our favorite lighting gizmo to give you even more flexibility when brightening up your life. Joining the bloated list of "world's smallest" gadgets, Rohm's latest LED, dubbed the PicoLED, comes in at just 1- x 0.8- x 0.2-millimeters in size, besting the previous title holder of 1.6- x 0.8- x 0.2-millimeters. The firm purportedly aims to pump out around 10 million of these bantam diodes per month when it hits mass production in April, and if you've got some serious buying power, you can pick these up for around ¥100 ($0.83) apiece and go absolutely wild.[Via PlasticBamboo]
