Nokia plugs itself into the Wireless Power Consortium

by Donald Melanson posted Oct 2nd 2009 @ 8:17PM

The Wireless Power Consortium has already managed to attract some pretty big players in the industry (including Philips, Sanyo and Duracell), but it's now bolstered its roster with one of its biggest heavyweights yet by announcing that Nokia has signed on as a full member. Of course, Nokia isn't making any firm promises about incorporating the Consortium's Qi wireless power standard into its products just yet, but it does say that the technology "carries significant potential to enhance consumer experience of battery charging," and that it "aims to meet these consumer expectations." For its part, the Wireless Power Consortium is unsurprisingly thrilled to have Nokia on board, noting that the move "significantly expands the potential market traction of the Qi wireless charging standard."

Nokia hopes to one-up Touchstone, harness wireless power for "ambient" phone charging

by Paul Miller posted Jun 9th 2009 @ 4:14PM

Like a page torn right out of the government's top secret files on Nikola Tesla, a Nokia research team is working on a wireless energy harvesting mechanism, which sucks up all that cancer-giving RF floating through the air and turns it into electrical current. Their goal is about to capture about 50 milliwatts of power for "ambient charging" -- which would at least be enough to top off the battery while the phone is off. Unfortunately, right now their current prototypes are only pulling down 3 to 5 milliwatts, and many in the industry are convinced it can't be done (don't worry, Nokia, that's just The Man, keeping you down). To be honest, we're not totally sure were comfortable with the thought that there's enough RF floating around to make this even theoretically possible, but as we slowly come to grips with our own mortality, we imagine we'd gladly pay an extra $70 or so for the privilege of never having to charge our phone again. Nokia itself isn't over promising: they plan on supplementing this juice with solar power, and thinks it'll be three or four years until it makes its way into a handset -- probably around the time your existing iPhone contract dries up.

Palm Pre Touchstone to be an entire product line, not just a charging dock

by Nilay Patel posted Apr 12th 2009 @ 5:11PM

Although Palm's reps basically stick to the same script when giving out those lengthy Pre walkthrough demos, every now and again they'll let something interesting slip -- like the fact that the Touchstone inductive charging dock is just the first product in an entire line of Touchstone wireless products. It's not clear if that simply means that "Touchstone" will be Palm's wireless power branding, or if there will be Touchstone products that do more than simply charge devices, but we're certainly eager to find out more -- and hopefully soon. Video clip after the break.

MWg and Splashpower team up for wireless charging of smartphones

by Sean Cooper posted Jan 30th 2008 @ 2:41PM

Mobile & Wireless Group (MWg) and Splashpower have joined hands in an effort to bring wireless charging to the mobile masses. Using electromagnetic induction instead of a traditional plug on the handset, by just dropping -- well, no need to actually drop it -- the handset on a Splashpower pad the built-in inductive charging components in the phone will begin to renew your battery without a need to actually plug it in. The first handsets are due out in the second half of the year and we're positively stoked to see one of these in action.

Seiko Epson, Murata team up on contactless quick charger

by Darren Murph posted Sep 29th 2007 @ 4:37AM

Not even a week after startup WiPower boasted about its breakthrough in wireless power, Murata and Seiko Epson have announced plans to "jointly development a non-contact quick charging system." Reportedly, the technology "leverages electromagnetic induction," and both the charging stand and a given mobile device would be "respectively equipped with coils that generate power." As for the production, it sounds like Seiko Epson will hone in on the "transmitting side, or primary side," while Murata "will be involved in the production of the rechargeable Li-ion." The overriding goal is to recharge a handset "in about 10 to 15 minutes in a non-contact manner," which would purportedly push power transmission efficiency from current levels of 30- to 50-percent to nearly 70-percent. Oh, and we've already been assured that these "will not generate heat."
