Believe It or Not—a Battery-Free Cell Phone
—Andrew Crosthwaite


Do you sometimes worry that your phone will run out of power right when you need it most? Wouldn't it be great if you never had to worry about charging your phone ever again?

It might sound impossible, but a team from the University of Washington has built a cell phone that doesn't need a battery. The phone is powered by radio waves that are sent from a base station, which can be up to 31 feet away. Additionally, power can be provided by light.

The phone is very simple. It has no screen or casing. It can't take pictures or send text messages, but it has a number pad and can handle voice calls. It works similarly to a walkie-talkie, as only one person can speak at a time.

The phone's designers hope that the base stations used to provide power will one day be a common wireless technology like Wi-Fi. Don't throw away your charger just yet, but a battery-free future for phones is now possible—and that's something to get energized about.

信不信由你:無電池手機時代來臨!
你有時會擔心你的電話在你最需要的時候沒電嗎?如果你再也不必擔心手機要充電,豈不是很棒?
這聽起來也許不太可能,但華盛頓大學的團隊已打造出不用電池的手機。這款手機是用基地台傳送過來的無線電波來提供電力,基地台最遠可達三十一英尺遠。此外,也能用光來充電。
這台手機很簡單。它沒有螢幕或外殼。它不能拍照或是傳簡訊,但是它有數字鍵盤,也可以處理語音通話。它作用就跟無線對講機類似,因為一次只能一個人講話。
手機設計者希望被用來供電的基地台有一天會是常見的無線科技,就像Wi-Fi無線網路一樣。還不要丟掉你的充電器,但未來手機不用電池如今已是可能的——那是讓人興奮的事情。
