German scientists recently developed a shoe that can tie its own shoelaces and use magnetic force to charge to assist people’s walking.
The British “Daily Mail” reported that a research team from the University of Freiburg in Germany has developed “smart shoes” with sensors and motors. The shoelaces can be automatically tied according to different sizes of feet. When you want to take off the shoes, tap the shoes. Just take it off. In addition, this kind of shoe can also capture the energy generated by foot movement through magnetism. In addition to this kind of shoes, Germany also developed shoes with compasses and navigators.
In the movie “Back to the Future”, we saw that Marty McFly’s Nike shoes can tie their own shoelaces. It has been 26 years now. This year, shoes that tie your own shoelaces have appeared, fulfilling a prediction about 2015 in the movie.
Engineers have designed shoes that tie themselves to suit the size of your foot. As long as you put on the shoes and press the button, the sensor will tell the “smart shoes” that you have put them on, causing the small motor at the heel to start and tighten the shoelaces. When you want to take off your shoes, you just tap the heels of the two shoes against each other twice, and the engine will relax the spring at the tongue, loosening the shoelaces so that you can take off the shoes.
This very ingenious invention does not even require charging or replacing batteries, because its motor is driven by collecting energy generated when walking.
Clevis Ili, an engineer at the Institute of Micromachines and Information Technology in southern Germany, said, “Such shoes are helpful for all kinds of people. They can help children and people who like fashion, but they are not suitable for those who have difficulty walking.” The elderly are more useful.”
This kind of shoe collects energy from the movement of the feet and charges it into a battery. An hour of walking is enough energy to tie the shoelaces once. But there is no need for energy when untying the shoelaces. You can just rely on the spring at the tongue. In addition, you can also use a wireless charging pad to fully charge the battery in the shoe.
Mr. Yi Li and a research team from the University of Freiburg published their design in the monthly magazine “Smart Materials and Structures”. They also developed a small device that can give shoes navigation functions. The device uses a compass, high-speed computing The device and gyroscope can determine the direction and tell which way to go while wearing shoes.
Designers hope that navigation shoes will help emergency departments navigate unfamiliar buildings.
In “Back to the Future II” published in 1989, Marty McFly wears self-lacing Nike shoes, stands on a floating board, and flies to 2015. This scene seems to have really come true.
