無線充電器定義：

無線充電(dian)器(qi)是指利用電(dian)磁(ci)(ci)波(bo)感應(ying)原(yuan)理進(jin)行充電(dian)的(de)(de)設備，原(yuan)理類(lei)似于變壓器(qi)。在(zai)發送(song)和接收(shou)端各有(you)(you)一個線圈(quan)，發送(song)端線圈(quan)連接有(you)(you)線電(dian)源(yuan)產生電(dian)磁(ci)(ci)信號，接收(shou)端線圈(quan)感應(ying)發送(song)端的(de)(de)電(dian)磁(ci)(ci)信號從而(er)產生電(dian)流給(gei)電(dian)池充電(dian)。

相(xiang)關報道

　　英國一(yi)家(jia)公司(si)發明了一(yi)種新型無線充電(dian)器，它看上去就像一(yi)塊(kuai)塑料(liao)鼠(shu)標墊，將手機(ji)等放在墊上就能(neng)充電(dian)，并能(neng)同時給多(duo)個設(she)備充電(dian)。

　　據22日(ri)出版的英國《新科學(xue)家》雜志報道，這個“鼠標墊”里裝有(you)密集的小型線(xian)圈(quan)陣列(lie)，可產(chan)生磁場，將能量傳輸(shu)給裝有(you)專用接收線(xian)圈(quan)的電子設備，進行充電。接收線(xian)圈(quan)由磁性合金(jin)繞以電線(xian)制成，大小和形狀都與(yu)口香糖相似，可以很方(fang)便地貼在電子設備上(shang)。

　　無線充(chong)電技術(shu)此前已經出現，但這項新發明更為(wei)方便實用(yong)。手機等(deng)設(she)備只要(yao)貼上(shang)(shang)(shang)接收(shou)線圈，放(fang)置在(zai)“鼠標墊(dian)”上(shang)(shang)(shang)的任一(yi)(yi)位(wei)置都可充(chong)電，不像以前的一(yi)(yi)些技術(shu)那樣需要(yao)精確定(ding)位(wei)。幾個設(she)備同時(shi)放(fang)在(zai)墊(dian)子上(shang)(shang)(shang)，可以同時(shi)進(jin)行(xing)充(chong)電。充(chong)電器產生(sheng)的磁場(chang)很弱，能夠給設(she)備充(chong)電但不會影響附近的信(xin)用(yong)卡、錄(lu)像帶等(deng)利用(yong)磁性(xing)記錄(lu)數據的物(wu)品。

 

發展歷史

　　早在19世(shi)紀(ji)30年代(dai)，邁克爾?法拉第就發現，周圍(wei)磁場(chang)的(de)變(bian)化(hua)將在電線中產生(sheng)電流。19世(shi)紀(ji)90年代(dai)，愛迪生(sheng)光譜(pu)輻射能研究項目的(de)一名(ming)助手尼古(gu)拉?特斯拉就申請了最初的(de)一個專利。

　　但(dan)遺憾(han)的是(shi)，這方面的研究(jiu)延遲(chi)了一個世(shi)紀。最大的障(zhang)礙是(shi)傳(chuan)(chuan)輸效率太低又(you)存在(zai)危險(xian)。電磁(ci)輻射只適(shi)合(he)傳(chuan)(chuan)送信息(xi)，并(bing)不適(shi)合(he)傳(chuan)(chuan)送能量(liang)。因為輻射無定向(xiang)性可(ke)言，能量(liang)將會浪費在(zai)無用的空間中。有(you)人設想使(shi)用定向(xiang)電磁(ci)輻射，比如激光，但(dan)其(qi)可(ke)操作性不強且極(ji)具危險(xian)性。

　　香(xiang)港(gang)城市大學電(dian)子工程學系許(xu)樹源教授在(zai)早幾(ji)年曾成功研制(zhi)出“無(wu)線(xian)電(dian)池(chi)充(chong)電(dian)平臺(tai)”，可將數個電(dian)子產品放在(zai)一個充(chong)電(dian)平臺(tai)上(shang)，不需(xu)外接電(dian)線(xian)，透過低頻電(dian)磁場(chang)自動(dong)充(chong)電(dian)，充(chong)電(dian)時間與傳統充(chong)電(dian)器無(wu)異。但這一技術仍需(xu)要(yao)(yao)產品與充(chong)電(dian)器接觸(chu)，它主要(yao)(yao)利用的是近場(chang)電(dian)磁耦合原理。

　　美國(guo)麻省理工學院的研究人員最(zui)近在無線傳輸(shu)電(dian)力方面取(qu)得了新進展，他們用兩米外的一個(ge)電(dian)源，“隔地”點亮了一盞60瓦的燈泡(pao)

　　索利亞契奇的(de)設計(ji)，非輻射無(wu)(wu)線能(neng)量傳輸有(you)距(ju)離的(de)限制(zhi)，接收器越(yue)小則這(zhe)(zhe)個距(ju)離越(yue)短(duan)。他計(ji)算出筆記(ji)(ji)本電(dian)腦大小的(de)物體可以(yi)在幾米的(de)范圍內接受(shou)無(wu)(wu)線能(neng)量傳輸，“這(zhe)(zhe)樣在每個房間(jian)安裝(zhuang)一(yi)個發射源，就可以(yi)給整個住(zhu)宅的(de)筆記(ji)(ji)本電(dian)腦供電(dian)了。”

　　索利(li)亞契奇希(xi)望通過使用不(bu)同材料和改(gai)(gai)進技術，把(ba)效率(lv)提高到70%至(zhi)80%。他(ta)們(men)相信，改(gai)(gai)進后的(de)設(she)備將在3到5年(nian)內為筆(bi)記本電(dian)腦(nao)、移動電(dian)話以及其他(ta)設(she)備進行無(wu)線(xian)充電(dian)。

編輯本段工作原理(li)

　　物(wu)(wu)(wu)理(li)學家早就知道，在(zai)兩個(ge)(ge)共(gong)振頻率相同的物(wu)(wu)(wu)體之(zhi)間(jian)能(neng)有(you)效地(di)傳輸能(neng)量，而不(bu)(bu)同頻率物(wu)(wu)(wu)體之(zhi)間(jian)的相互作用較弱(ruo)。歌唱家演唱能(neng)將裝有(you)不(bu)(bu)同水量瓶(ping)子中(zhong)的一個(ge)(ge)震碎，而不(bu)(bu)影響(xiang)其他瓶(ping)子就是這(zhe)個(ge)(ge)道理(li)。這(zhe)也好比我們(men)蕩(dang)秋(qiu)千時，只需坐在(zai)上面讓下垂的雙(shuang)腿同步擺動就能(neng)給秋(qiu)千帶來(lai)動力一樣(yang)。

無線充電(dian)技(ji)(ji)術正是利用(yong)了這個原(yuan)理。同樣，無線充電(dian)技(ji)(ji)術也應(ying)用(yong)了電(dian)磁(ci)波感應(ying)原(yuan)理，及相關(guan)的(de)交流(liu)感應(ying)技(ji)(ji)術，在發送和接(jie)收端用(yong)相應(ying)的(de)線圈(quan)來發送和接(jie)收產(chan)生感應(ying)的(de)交流(liu)信號來進行(xing)充電(dian)的(de)的(de)一(yi)項(xiang)技(ji)(ji)術， 用(yong)戶只(zhi)需要將充電(dian)設備放在一(yi)個“平板”上即可進行(xing)充電(dian)，這樣的(de)充電(dian)方式過去曾(ceng)經出現在手表和剃須刀(dao)上，但是當時無法(fa)針對大容量(liang)鋰離子電(dian)池進行(xing)有效充電(dian)。無線充電(dian)器技(ji)(ji)術原(yuan)理構圖如(ru)圖所示

　　最初由英國一家公司發明了一種新型無線充(chong)電(dian)(dian)器(qi)，它(ta)看上(shang)去就(jiu)像一塊塑料鼠(shu)標墊(dian)，這個“鼠(shu)標墊(dian)”里(li)裝(zhuang)有密(mi)集的(de)小(xiao)型線圈(quan)陣列，可產生磁場，將能量(liang)傳輸給裝(zhuang)有專用接收線圈(quan)的(de)電(dian)(dian)子(zi)設備(bei)(bei)，進行充(chong)電(dian)(dian)。接收線圈(quan)由磁性(xing)合(he)金繞以電(dian)(dian)線制成，大小(xiao)和形狀都與口香糖相似，可以很(hen)方(fang)便地貼在電(dian)(dian)子(zi)設備(bei)(bei)上(shang)。將手機(ji)等放在墊(dian)上(shang)就(jiu)能充(chong)電(dian)(dian)，并能同時(shi)給多(duo)個設備(bei)(bei)充(chong)電(dian)(dian)。

無線(xian)充(chong)(chong)電(dian)(dian)技術(shu)此(ci)前已(yi)經出現，但這項(xiang)新發明(ming)更為方便實(shi)用(yong)。手機等(deng)設(she)備只要貼(tie)上(shang)接收線(xian)圈(quan)，放(fang)置在(zai)“鼠標墊(dian)”上(shang)的(de)(de)(de)任一(yi)位(wei)置都可(ke)充(chong)(chong)電(dian)(dian)，不像(xiang)以(yi)前的(de)(de)(de)一(yi)些技術(shu)那(nei)樣需要精確定位(wei)。幾個設(she)備同(tong)時放(fang)在(zai)墊(dian)子上(shang)，可(ke)以(yi)同(tong)時進行充(chong)(chong)電(dian)(dian)。充(chong)(chong)電(dian)(dian)器產生的(de)(de)(de)磁(ci)場(chang)很弱(ruo)，能夠給設(she)備充(chong)(chong)電(dian)(dian)但不會影響附近(jin)的(de)(de)(de)信用(yong)卡、錄像(xiang)帶(dai)等(deng)利用(yong)磁(ci)性(xing)記錄數據的(de)(de)(de)物品。

編(bian)輯本段輻射

　　麻省(sheng)理(li)工學院的研究人(ren)(ren)員表(biao)示，身體(ti)對(dui)(dui)電(dian)場的反(fan)應很強(qiang)，但身體(ti)對(dui)(dui)磁場的反(fan)應則幾乎沒(mei)有，因此這一系統不會影響人(ren)(ren)體(ti)健康。不過(guo)，這還只(zhi)是(shi)一種推(tui)測，有研究人(ren)(ren)員對(dui)(dui)此觀點(dian)表(biao)示擔(dan)心，在真正應用于(yu)生活(huo)前(qian)，還需要進一步(bu)進行(xing)試驗。

　　做為電子類充電產(chan)品(pin)，充電器本身(shen)避免(mian)不了輻(fu)射(she)，所以無線充電器有(you)輻(fu)射(she)是必(bi)然的。但是目前無線充電器的功率(lv)很(hen)小，充電時間較長，所產(chan)生的輻(fu)射(she)也小，應該不會對人產(chan)生較大的傷害。
