據國外媒體報道，最(zui)近(jin)，日(ri)本(ben)富(fu)士(shi)通(tong)公(gong)司(si)揭(jie)開(kai)了(le)一(yi)項(xiang)充(chong)電(dian)技(ji)術(shu)的(de)神(shen)秘(mi)麵(mian)紗(sha)，可(ke)利(li)用(yong)磁(ci)鐵(tie)立(li)即(ji)為(wei)一(yi)個(ge)以(yi)上(shang)的(de)設(she)備(bei)充(chong)電(dian)並(bing)且(qie)完(wan)全(quan)不(bu)借(jie)助(zhu)電(dian)線(xian)。這(zhe)項(xiang)技(ji)術(shu)允(yun)許(xu)設(she)備(bei)在(zai)距(ju)離(li)充(chong)電(dian)器(qi)最(zui)遠(yuan)可(ke)達(da)幾(ji)米(mi)遠(yuan)的(de)地(di)方(fang)進(jin)行(xing)無(wu)線(xian)充(chong)電(dian)
，同(tong)時(shi)也(ye)將(jiang)促(cu)使(shi)日(ri)本(ben)政(zheng)府(fu)在(zai)2012年之前在公共場所設置無線充電網點。

從cong理li論lun上shang說shuo，這zhe一yi係xi統tong對dui處chu在zai充chong電dian場chang的de人ren完wan全quan無wu害hai

，因yin為wei電dian量liang隻zhi在zai以yi同tong一yi頻pin率lv共gong振zhen的de線xian圈quan之zhi間jian傳chuan輸shu。但dan對dui於yu這zhe種zhong無wu線xian充chong電dian技ji術shu

，很hen多duo人ren可ke能neng產chan生sheng擔dan憂you，就jiu像xiang當dang初chu對duiWi-Fi和手機天線杆一樣。

最近幾年，隨著iPhONe、iPad等對電量充滿“饑渴”的設備迅速興起

，研發無線充電等突破性充電技術的需求日益提高。富士通在一份聲明中說：“zhexiangjishujiangweishoujijihejincouxingwuxianchongdiangongnengyijitongshiweiduogebianxieshishebeichongdianpupingdaolu。duiduogeshebeichongdianshi，shebeixiangduiyuchongdianqideweizhimeiyourenhexianzhi。”

當dang前qian的de很hen多duo無wu線xian充chong電dian係xi統tong依yi靠kao線xian圈quan之zhi間jian的de電dian磁ci感gan應ying
，這zhe種zhong方fang式shi工gong作zuo距ju離li太tai短duan
，設she備bei需xu要yao放fang置zhi在zai充chong電dian座zuo上shang，同tong時shi也ye會hui消xiao耗hao大da量liang電dian量liang。富fu士shi通tong的de充chong電dian係xi統tong立li基ji於yu磁ci共gong振zhen，電dian量liang可ke以yi在zai以yi同tong樣yang頻pin率lv發fa生sheng共gong振zhen的de線xian圈quan之zhi間jian進jin行xing無wu線xian傳chuan輸shu。

測試結果顯示無線傳輸距離大約在15厘(li)米(mi)左(zuo)右(you)，但(dan)富(fu)士(shi)通(tong)表(biao)示(shi)無(wu)線(xian)傳(chuan)輸(shu)距(ju)離(li)最(zui)終(zhong)可(ke)實(shi)現(xian)幾(ji)米(mi)遠(yuan)。需(xu)要(yao)指(zhi)出(chu)的(de)是(shi)，距(ju)離(li)設(she)備(bei)越(yue)遠(yuan)
