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

It’s been 26 years since we saw them magically tightening Marty McFly’s Nike boots in the film Back to The Future

Nowself-tying shoelaces could actually become a reality this yearproving right one of the film’s fantastical predictions for what 2015 would be like

Engineers have designed a shoe that can automatically lace upadjusting itself to the shape of your foot

Simply slip the controller on and pressure sensors will tell the ‘smart shoe’ when your foot is in positiontriggering(触发)a tiny motor in the heel that pulls the laces tight.

When you want to take off the shoesyou click your heels together twice and the motor will release a spring(弹簧)in the shoe’s tonguewhich loosens the laces enough for you to slip them off

And the invention doesn’t 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 K1evis Ylliof the Institute for Micromachining and Information Technology in southern Gemanysaid 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 childrenor as a lifestyle product

The designwhich is still in a prototype(雏形)stagecleverly gets the energy of the foot’s swing when opposing magnets in each shoe move past each other. It then uses that power to charge a batteryAn hour of walking is enough to tighten the laces onceand it requires no energy to undo the shoes because that relies on the spring alone.
