Hasta La Gadget!

The Google Nexus 4 Pure Android smartphone has been available for some time, and for those lucky enough to get one before the supply crunch (it’s back on the Google Store now), they may be happy to learn that the official Wireless charger is now available for order, and should ship “soon”  according to the Google Play Store (soon = less than one week?).

The Power Matters Alliance, which is a wireless power standards group formed by Duracell’s Powermat and Procter & Gamble (parent company of Duracell), is aiming to create wireless power standards for smartphones and other devices under the IEEE’s guidelines. Big companies such as AT&T, Google, and Starbucks have signed up and are now backing the group.

However, the Power Matters Alliance is facing stiff competition from other wireless power standards groups, such as the Alliance for Wireless Power and the Wireless Power Consortium. The WPC is pushing for the Qi standard, which is PMA’s biggest rival and it’s also backed by a number of large hardware vendors like Samsung, Motorola, LG, and HTC.

However, now that AT&T, Google, and Starbucks are on board at PMA, the alliance could make some solid progress in their pursuit for a wireless power standard. Starbucks is planning to pilot a new program where it will bring Duracell Powermat charging stations to 17 Boston locations, and it could lead to a nation-wide rollout in the future.

Not only will the addition of more big-name companies help out the alliance, but the companies themselves that formed the alliance (like Duracell) will see a major boost in publicity and sales. Other companies that are backing PMA include Delta Airlines and General Motors, as well as celebrities like Jay-Z and big-name attractions like Madison Square Garden in New York City.

Nokia thinks you’ll like the wireless phone charging on your Lumia 920 or 820 enough to want to take it on the road, and to that end it’s striking a deal to bring the cable-free experience beyond the home. Both Virgin Atlantic’s lounge at Heathrow Airport and countertops at The Coffee Bean & Tea Leaf in the US will let you top up your Windows Phone without having to hunt for a power outlet. We’re still waiting on details like the timing, but we’re glad to know that we won’t have to lug around our FatBoy Recharge Pillows just to keep living in Nokia’s vision of the future.

That was quick: we’d heard rumors through The Verge of wireless charging coming to the repeatedly leaked Lumia 920 alongside a pseudo-PureView camera, and the mysterious @evleaks has come through with what looks to be press photos showing the wireless charging pad in action. As long as they’re more than just wild imaginings, they reveal a puck-like surface that could juice up both the Lumia 920 and the less ambitious 820. We don’t know much more about the charger, although it’s expected to use Qi and wouldn’t limit the phones and pad to coupling solely with each other. We’ll know the bigger picture on September 5th; in the meantime, check after the break for a bonus picture showing both Windows Phone 8 devices with an unnamed Bluetooth headset (likely a Luna variant) that might join the charger in Nokia’s accessory line.

Batteries used to be the only way to power implantable gadgets, but additional surgeries are needed to replace the power packs once their juice runs out — a less-than-ideal solution for patients. Recent discoveries, however, have such medgadgets being powered by photons, hip hop and now high-frequency radio waves. Electrical engineers at Stanford built a cardiac device that uses a combination of inductive and radiative transmission of power, at about 1.7 billion cycles per second, to its coiled receiving antenna.

Previous prevailing opinion held that the high frequencies needed for wireless power delivery couldn’t penetrate the human body deep enough, and the lower frequencies that would do the trick require antennas too large to work as implants. That conundrum was solved by getting the high-frequency signals to penetrate deeper using alternating waves of electric and magnetic fields. That allowed a 10x increase in power delivery — up to 50 microwatts to a millimeter radius antenna coil — to an implant five centimeters below the skin. That antenna also was also designed to pull power regardless of its orientation, making it ideal for applications inside always-moving human bodies. Of course, the implant’s really just a proof-of-concept at this stage, but hopefully it won’t be long before battery powered implants go the way of the dodo TouchPad.
