Transparent graphene speakers printed with inkjets, lo-fi musical windows are on their way

Transparent Graphene Speaker

Add that magical material known as graphene to the list of things you can make with inkjet printers alongside OLEDs, solar panels, and light-bending metamaterials. Scientists at the Seoul National University used printers and a technique known as vapor deposition to leave a thin film of the graphite-based conductor on sheets of PVDF (poly vinylidene fluoride). By sandwiching the the PVDF between graphene electrodes and applying a current from a sound source researchers were able to create a flat and transparent loudspeaker that could be integrated into windows or screens. Don’t expect this low-power sound source to replace your hi-fi though — since it relies on the distortion-prone piezoelectric effect, it probably won’t sound much better than the earpiece on your cellphone.

SK Telecom and LG U+ launch LTE in Seoul, fellow South Koreans seethe with envy

Frustrated by a lack of choice amongst LTE carriers? We sympathize, so join us while we ponder a relocation to Seoul where not one, but two major telcos — SK Telecom and LG U+ — have enabled access to the high speed protocol. Service began on July 1st for data devices (read: modems) while phones from Samsung and LG are scheduled to make an appearance this fall. While those in Seoul are already surfing at higher speeds, the LTE wave is slated to go nationwide by 2012 for U+ subscribers and in 2013 for those on SK. Still not enough 3GPP goodness for you? Add the nation’s third major carrier KT and their Q3 LTE trials to the mix, and we’ll know where to send you next time you’re hankering for delectable download speeds with a side of spicy kimchi.

South Korea plans to convert all textbooks to digital, swap backpacks for tablets by 2015

Well, that oversized Kindle didn’t become the textbook killer Amazon hoped it would be, but at least one country is moving forward with plans to lighten the load on its future generation of Samsung execs. South Korea announced this week that it plans to spend over $2 billion developing digital textbooks, replacing paper in all of its schools by 2015. Students would access paper-free learning materials from a cloud-based system, supplementing traditional content with multimedia on school-supplied tablets. The system would also enable homebound students to catch up on work remotely — they won’t be practicing taekwondo on a virtual mat, but could participate in math or reading lessons while away from school, for example. Both programs clearly offer significant advantages for the country’s education system, but don’t expect to see a similar solution pop up closer to home — with the US population numbering six times that of our ally in the Far East, many of our future leaders could be carrying paper for a long time to come.

Apple sues Samsung again for copying the iPhone’s design, this time in South Korea

As if Apple and Samsung’s patent infringement catfight weren’t distracting enough, Apple is recreating the legal spectacle in Samsung’s home country of South Korea. Apple just filed a suit against Samsung Electronics in Seoul Central District Court, with Cupertino alleging that the Samsung Galaxy S copies the third-generation iPhone, according to a report from the online news site, MoneyToday. That closely matches the claims Apple made when it it sued Samsung back in April for “slavishly” copying the iPhone and iPad. Since then, Apple’s expanded its case to include additional Samsung devices, including the Droid Charge, Infuse 4G, Nexus S 4G, Galaxy Tab 10.1, Galaxy S II, and a handful of others. Meanwhile, Samsung has attempted (in vain) to subpoena prototypes of Apple’s next-gen iPhone and iPad. We wouldn’t be surprised if Samsung abandoned its efforts to peek Apple’s forthcoming products, but if this is, indeed, destined to be a case of déjà vu, Samsung might well strike back with a suit of its own.

Kiro robot teaches Korean kindergarten by day, discusses Kandinsky by night

This little girl loves Kiro. Why? Because he’s probably the raddest robot teacher she’s ever seen. Developed by Korea’s Robot Research Institute, the bot recently wrapped up a three week trial period in a kindergarten classroom, where he apparently spent most of his time screening educational videos on his abdomen, playing interactive games, and keeping his students in rapt attention. When he wasn’t busy dishing out Ritalin to his underlings, Kiro also served as a guide at the Dong-A University Museum, in Busan. After programming the droid with enough knowledge to make him sound smart, engineers set him loose within the art gallery, where he would provide visitors with background information in hushed, docent-dulcet tones. He loves kids. He loves art. He’s always smiling. He’s the kinda bot you could bring home to Dad. Scope him out for yourself in the video, after the break.

Samsung brings Van Gogh ‘paintings’ to Korea via Smart TV, makes us reach for the absinthe

This is sort of strange. People in Korea are looking at masterpieces of Western art on a TV screen — and not from the comfort of their laptops. It’s all part of something called Rêve et Réalité (Dream and Reality), a Samsung-sponsored exhibition that brings some of the world’s most celebrated works to Seoul’s Hangaram Museum via four, 46-inch LEDs. The expo, on display until September, features some of the greatest hits from Claude Monet, Jean F. Millet and, most notably, Van Gogh, whose Starry Night has never been on display in Korea (and, as far as we’re concerned, still hasn’t). Televised docents provide background info on the artists, whose paintings are all transmitted via a giant Smart TV video wall that blurs out all semblance of texture and nuance — much like that bottle of absinthe we’re about to pound.

Sony promises global PSN restoration by week’s end, except in some parts of Asia

It looks like Sony’s long, PSN nightmare is finally coming to an end — almost. Today, the company announced that it will restore PlayStation Network and Qriocity services in the Americas, Europe and most of Asia by week’s end. The only exceptions are Hong Kong, South Korea and Japan, where users will have to await further details before regaining full access. Speaking to the Wall Street Journal, spokeswoman Yuki Kobayashi added that Sony is in the process of finalizing an agreement to protect credit card owners in these three countries, where authorities have taken a particularly cautious approach to the data breach. This means that the company won’t see global restoration by the end of May, as previously hoped, but Kobayashi said the plans were delayed simply because Sony needed more time to fully secure its infrastructure (sound familiar?). You can read a lengthier explanation in the press release after the break.

Sony says PlayStation Network will return to Asia, starting tomorrow

Good news, Asia — the PlayStation Network is finally coming back. Today, Sony announced that it will restore its gaming network across the continent, more than a month after falling prey to a crippling data breach. The company’s PSN services are already up and running across other parts of the world and, beginning tomorrow, will light up once again in Taiwan, Singapore, Malaysia, Indonesia, Thailand and even Japan, which had been harboring serious reservations about the network’s security. Gamers in South Korea and Hong Kong, meanwhile, will have to wait a little longer before returning to normalcy, though Sony is hoping to completely resolve the issue by the end of the month. The company certainly seems eager to put this saga to bed, and for understandable reasons. The incident has already cost Sony an estimated $171 million in revenue — not to mention the untold numbers of suddenly wary consumers.

LG Optimus 2X scoops up Guinness World Record for being first dual-core smartphone

LG’s Optimus 2X just scooped up official recognition from the Guinness World Records crew for being the very first dual-core smartphone, which sounds like a good thing, but really it kind of isn’t. In its rabid pursuit of the “First!” badge, LG neglected to polish up the 2X’s software, leaving a lot of early users feeling high, dry, and in need of a good custom ROM. On the other hand, that very same phone’s US variant, the T-Mobile G2x that came a couple of months later, arrived with a nice and shiny stock Android build that really showed off the underlying hardware’s true capabilities. So yeah, kudos on another Record, LG, but next time let’s have less haste and more awesome, mmkay?

Samsung SENS-240 Navigation Tablet is strange and familiar

It’s been a few years but iriver just released an updated version of its NV GPS navigator with SPINN UI. Wa… wait a second, that’s a Samsung logo. Sorry, this is the Samsung SENS-240, a hybrid car navigation system / tablet that plays nice with your Android-powered Samsung smartphone or, uh, tablet. According to Akihabara News, the SENS-240 uses Bluetooth to take over your voice, data, voice search, and even “video features” from your smartphone when driving. You can then control the SENS-240 using your smarpthone or tablet as an “advanced” remote when idle. The details behind how this works, or why you’d want to do it, is a mystery. We do know that the SENS-240 comes packing 256MB of RAM, USB-host mode, and an SD slot in addition to a 1.43GHz processor (of unknown origins) said to be powerful enough to handle 3D maps, video, or DMB TV on that 7-inch, 800 x 480 pixel display. Oh, and it’s Korea-only for now.
