Wire-free 無線的科技生活


(Powermat wire-free device 請點圖看影片)

筆者在2003年曾經報導過MobileWise的Wire-free device, 當時這個產品的出現真的令人驚豔, 終於可以擺脫3C產品那麼多規格的充電器, 但是幾年過後MobileWise突然消聲匿跡, 當時另外一家Splashpower也同樣莫名其妙的消失, 到底發生了什麼事呢?

根據WildCharge的Matzkevich(當時MobileWise的Marketing VP)說, 當時的製造成本與現在差異太大了, 因此當時的製造技術根本無法生存, 這裡有WildCharge在CES上的影片

除了WildCharge外, 同樣是Wire-free的供電設備還有PowerCast, eCoupledPowermat,這裡有關於PowerCast的介紹eCoupled的介紹

不管是Powermat, PowerCast, Wildcharge, 或是eCoupled, 都是無線式的電源設備, 提供給lower-power device, 如3C產品/電視/電燈/玩具...等

Powermat使用的是Powermat’s surface connect technology™ (SCT)專利技術, PowerCast使用的是Powercaster™ transmitter chip與Powerharvester™ receiver chip, 透過RF(Radio Frequency)來傳送訊號與充電, WildCharge則與Powermat的技術及應用比較類似, eCoupled則與PowerCast的技術及應用比較類似

有興趣的讀者, 可以看CES 2007CES 2008詳細內容

Firstly, Wildcharge is not wireless. They still use conductive power transfer, which is NOT much different from normal chargers.

Powercast uses far-field radiation. It can only transfer the power of tens or hundreds of milli-watts, which is not enough to charge a mobile phone. But it may be applied to LED.

Powermat and Ecoupled are similar, they use inductive coupling which was firstly introduced by Tesla more than 100 years ago. However, many technical problems need to be solved before commercializing Tesla's ideas. For example, making it as thin as possible (for easy integration), safety, radiation (this is important),.... Think about it. Not so easy.

Another company: ConvenientPower, for your reference.

Thanks for your comments, although I don't agree with some of your views.

Have a nice day!!
