Wireless Charging

Daimler will supply a Mercedes-Benz A-Class E-CELL, a second generation smart fortwo elect...

Inductive charging devices are already making their way into the home as a cable-free option to keep the batteries of everything from mice and keyboards to mobile phones and toothbrushes juiced up. The increasing availability of practical electric vehicles has also seen the technology attract the attention of those looking for for a cable-free way to charge EV batteries. German automakers are taking the opportunity to put inductive charging of EVs to a real-world test as part of the "Effizienzhaus-Plus mit Elektromobilität" project.  Read More

The Philips Sonicare DiamondClean Toothbrush charges when placed in the included rinsing g...

Oral hygiene has come a long way from the twigs, bird feathers and animal bones our ancestors used to clean their teeth. The first recorded toothbrush in history consisting of a twig with a frayed end called a chew stick dates back to 3,000 BC but toothbrushes have since evolved to include electric toothbrushes that move the brush head more rapidly than our puny wrists can manage. Such devices of course require charging, which usually means a charge station taking up valuable real estate on the bathroom counter alongside a rinsing glass. Now Philips has released a toothbrush that charges when placed in a glass that can still be used to rinse your mouth after brushing.  Read More

'Dynamic Charging' technology would see electric race cars (such as this Peugeot EX1, perh...

As some Gizmag readers will already know, the new technical regulations for Formula One racing state that cars must move under electrical power only when in the pit lanes. Eyebrow-raising though that may be, two companies are currently collaborating on technology that would see cars being powered by electric motors for the entire race. Instead of looking at ultra-powerful batteries or three-hour recharging pit stops, however, they're taking another approach - they propose that the cars could wirelessly receive power from transmitters embedded in the track.  Read More

An experimental wireless power system could reduce infections in patients with implanted h...

While implantable heart pumps may buy some time for people waiting to undergo heart transplants, such implants have at least one serious drawback – because they receive their power from an external source, a power cord must protrude through the skin of the patient’s belly. About 40 percent of patients experience infections of that opening, which often require rehospitalization, and in extreme cases can even cause death. The presence of that cord also makes it impossible for patients to swim or take baths. Researchers from the University of Washington and the University of Pittsburgh Medical Center are attempting to put an end to the troublesome cords, however, by developing a system that wirelessly transmits power to heart pumps.  Read More

Duke University scientists have outlined a theory for the use of metamaterials in facilita...

The weird properties of artificially engineered metamaterials are at the core of research into invisibility cloaking, but engineers from Duke University in North Carolina suggest that these materials could also provide a boost to another of technology's quests - wireless power transmission. In this latest hard-to-get-your-head-around metamaterial scenario, it's not the cloaked object that "disappears" - it's the space between the charger and the chargee.  Read More

Mobee's Magic Bar wireless charger for Apple's Bluetooth Keyboard and Magic Trackpad

Going wireless with your keyboard and mouse might unleash you from the shackles of cables, but at the price of having to constantly shell out for batteries or swap rechargeables in and out. Inductive chargers like the Powermat have provided a convenient, cable-free way to keep mobile phones, portable games consoles and PMPs powered up, and now Mobee has launched the first inductive charger developed specifically for the Apple Bluetooth Keyboard and Magic Trackpad.  Read More

BLAZE Induction Charger for the Nintendo Wii Mote

The arrival of viable wireless charging solutions has given us the opportunity to pull the plug on devices like mobile phones and personal media players (with televisions and electric vehicles next in line). Game controllers are another obvious candidate for this technology and BLAZE's latest offering joins the ranks of wireless-charging solutions for the Nintendo Wii remote.  Read More

LG has announced a Wireless Charging Pad for mobile phones

Wireless charging solutions for mobile devices have been trickling onto the market in the last couple of years and now industry heavyweight LG has announced that it's joining the sans-cable party with its own Wireless Charging Pad.  Read More

Look - no wires: the Fujitsu wireless monitor on display at CeBIT 2011

Many of us can now wirelessly stream images from a computer to a screen over Bluetooth or Wi-Fi without too much trouble, but the display is still inevitably powered by cables. At CeBIT 2011, Fujitsu is showing off a working prototype of a 22-inch computer display that receives both images and power wirelessly. The power transfer is made possible by magnetic induction technology – similar to Powermat chargers – that's concentrated into hotspots built into office furniture or conference tables.  Read More

The TI bqTESLA wireless charging development kit lets designers integrate wireless power t...

Between Bluetooth, Wi-Fi, and the latest-gen cell phone networks, we hardly ever have to plug anything into our mobile devices these days. That is, until the batteries die. Then we’re rooting through a rat’s nest of USB cables and adapters trying to find the right wall wart and a plug that fits the charging port. Clearly wireless charging’s day has arrived, and Texas Instruments has released the industry’s first Qi-certified wireless power development kit. The bqTESLA kit is meant to help design engineers integrate wireless power technology into devices such as smartphones, digital cameras, and MP3 players.  Read More
