Following NIKE After the company plans to launch smart high shoe like the science fiction movie "return to the future II", German researchers are also working on the development of automatic lacing shoes. According to the British mirror magazine January 15th, German researchers developed an automatic lacing shoe. Put on the shoe, step on the sensor installed in the shoe, the small motor of the sole will work and tighten the shoelace.

When you take off your shoes, touch the two heels lightly for two times and touch the "Dorothea" sensor on the heel. The shoe will release the spring to release the shoelace, so that you can take off your shoes.

Compared with the upcoming NIKE company Intelligence McGee's shoes need to be recharged. The automatic lacing shoes designed by German researchers are more "tall and up", which can generate energy without charging. The shoe is equipped with an energy harvesting system that spanforms the energy of the user's movement into electricity. HSG-IMIT, the famous German Institute, has developed two types of energy harvesters. One of them is "swing collector", which is specially made for this shoe. It is positioned at the bottom of the automatic lacing shoe. When the foot of the user swings by movement, it moves the magnet between the online loops and generates electric current. The swinging sensor will collect and store these energy for shoes.

Another name is "vibration collector". Its volume and weight are greater than the former. It is developed for some specific needs and will be applied to indoor navigation systems for military personnel and fire fighters.

However, at present, the two kinds of harvester do not achieve ideal results in energy collection, so the Institute's scientific research People plan to improve their efficiency.
