A team of scientists from University of Freiburg in Germany are developing a shoe with a sensor to automatically tie its laces that could be taken off when users click their heels together.

Its been 26 years since we saw them magically tightening Marty McFlys Nike boots in Back to The Future Part Ⅱ.

Now， self-tying shoelaces could actually become a reality this year， proving right one of the films fantastical predictions for what 2015 would be like.

Engineers have designed a shoe that can automatically lace up， adjusting itself to the shape of your foot.

Simply slip the trainer on and pressure sensors will tell the “smart shoe” when your foot is in position， triggering a tiny motor in the heel that pulls the laces tight.

When you want to take off the shoes， you click your heels together twice and the motor will release a spring in the shoes tongue， which loosens the laces enough for you to slip them off.

And the ingenious invention doesnt even need to be plugged in to charge or have its battery replaced because it runs on power generated by the swing of your foot as you walk.

Engineer Klevis Ylli of the Institute for Micromachining and Information Technology in southern Germany， said the shoes could help a variety of different people.

“One focus is that it could be used in shoes for elderly people who have mobility problems，” he said. “But it could also work for children， or as a lifestyle product.”

The design， which is still in a prototype phase， cleverly captures the energy of the foots swing when opposing magnets in each shoe move past each other. It then uses that power to charge a battery. An hour of walking is enough to tighten the laces once， and it requires no energy to undo the shoes because that relies on the spring alone.

德國弗萊堡大學(xué)的一個科學(xué)家團(tuán)隊正在研究一種可利用傳感器自動系鞋帶的鞋，而當(dāng)使用者碰撞鞋跟時，鞋帶就能自動解開。

距我們在電影《回到未來2》里看到馬丁·麥克弗萊的耐克鞋自動系鞋帶的神奇情景，已經(jīng)有26年了。

如今，假如電影中對2015年的虛構(gòu)預(yù)言有一個能成真的話，自動鞋帶今年可能真會成為現(xiàn)實。

工程師們設(shè)計出一款鞋可以自動系鞋帶，并可根據(jù)腳型自動調(diào)節(jié)。

當(dāng)你的腳穿進(jìn)去時，只需滑動控制器，壓力傳感器就會告知“智能鞋”，觸發(fā)鞋跟的小發(fā)動機(jī)將鞋帶系緊。

當(dāng)你想要脫鞋時，碰撞鞋跟兩次，發(fā)動機(jī)就會釋放鞋舌部位的彈簧，它會松開鞋帶讓你脫鞋。

這項獨創(chuàng)性的發(fā)明甚至無須充電或更換電池，因為它靠的是你走路時雙腳的擺動來發(fā)電。

德國南部微加工和信息技術(shù)研究所的工程師克賴維斯·伊利表示，這種鞋可以幫助很多不同的人。

他說：“值得注意的是，這種鞋帶可用于供行動不便的老年人使用的鞋，但它也可以供孩子使用，或者作為一種生活產(chǎn)品?！?/p>

目前，這項設(shè)計還是雛形。當(dāng)兩只鞋中極性相反的磁鐵互相移動時，它能巧妙地從中獲得能量。然后它將這些能量用于給電池充電。走一個小時的路產(chǎn)生的電量足以系緊鞋帶一次，而解鞋帶時因為只需依靠彈簧，因此無須能量。

Millennium Bridge

倫敦千禧橋

Location： St. Pauls

拍攝地點：圣保羅

It took a really long time to stop the Millennium footbridge wobbling， and the Death Eaters just knocked it down. Happily， its standing again now and you can walk across it without （much） fear. From the bridge you can just spy the Gothic spires of the Houses of Parliament， past which Harry and his fellow members of Dumbledores army whizz on broomsticks in The Order Of The Phoenix.

花了很長時間才讓千禧人行橋不再晃晃悠悠，而食死徒直接就這么把它擊沉了。值得高興的是，如今它屹立如初，你可以不（那么）膽戰(zhàn)心驚地走上橋去。橋上你可以探查到英國國會大廈的哥特式尖頂，這也是《哈利·波特與鳳凰社》里哈利和鄧布利多軍團(tuán)的人騎著掃帚嗖嗖飛過的地方。

Professor Flitwicks Classroom

弗立維教授的教室

Location： Harrow School

拍攝地點：哈羅公學(xué)

Hogwarts tiny Charms professor， Filius Flitwick， instructs his pupils in the art of Wingardium Leviosa in Harrow Schools oldest classroom， the Fourth Form Room that dates back to 1615. Harrow has lots in common with Hogwarts： some natty uniforms and a direct train from Kings Cross...

霍格沃茨體形嬌小的魔咒課教授菲利烏斯·弗立維在哈羅公學(xué)最古老的教室指導(dǎo)學(xué)生“羽加迪姆-勒維奧薩（懸浮咒）”的奧妙，這間第四教室可追溯到1615年。哈羅公學(xué)和霍格沃茨之間有很多的共同點：幾套整潔漂亮的制服，從國王十字站直達(dá)的火車……

Ministry Of Magic

魔法部

Location： Great Scotland Yard

拍攝地點：大蘇格蘭場

As Rufus Scrimgeour （Bill Nighy） intones at the beginning of The Deathly Hallows， its a time of murder， disappearances and raids， so its fitting that the Ministry of Magics exterior shots were filmed at Great Scotland Yard. Sadly， you wont find the red phone box that Harry and Ron use to enter the Ministry in The Order Of The Phoenix， but， as youll discover in The Deathly Hallows， theres a new route in anyway.

就如《哈利·波特與死亡圣器》一開頭魯弗斯·斯克林杰（比爾·奈伊飾）吟誦的那樣，謀殺、絕滅和突襲的時候到了，所以魔法部的外景鏡頭在大蘇格蘭場拍攝再合適不過。很遺憾的是，你并不會找到哈利和羅恩在《哈利·波特與鳳凰社》中進(jìn)入魔法部的那個紅色電話亭，但是，就像在《死亡圣器》里你會看到的那樣，無論如何都是有新路線的。
