Automatic Lacing Shoes Can Be Generated By Walking.

Following NIKE's plan to launch smart high shoe like the science fiction movie "back to the future II", German researchers are also working on the development of automatic lacing shoes.

According to the January 15th news of the British mirror, German researchers have developed an automatic tie 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 NIKE's upcoming intelligent MCG shoes, it needs recharging function. The automatic lacing shoes designed by German researchers are more "tall", which can generate energy without charging.

The shoe is equipped with an energy harvesting system that pforms the energy of the user's movement into electricity.

The famous Institute HSG-IMIT has developed two types.

。

One of them is "swing collector", which is specially made for this shoe.

It is housed in

At the bottom, when the user's foot swings because of the movement, the magnet will move between the coil and generate current. The swing 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 types of harvester have not achieved ideal results in energy harvesting, so the researchers of the Institute plan to improve their efficiency.

The size of the shoe and the shoe last are the basic choice, but the shoe type of each shoe factory is different.

For example, Adidas's last is usually relatively narrow, and ASICs is usually relatively wide. Different brands may be half or half last, so they can't be judged only by size, or if they are actually crossed.

When the foot touches the ground, it moves on the inside of the foot with the medial side of the foot. At last, it slightly leaning back to the middle of the front foot. It may be completely moving inside the sole of the foot.

This situation is more common in runners with low arch or flat feet. It needs stable structure to support the medial arch of the arch. The shoes selected are mainly of stable type.

Excessive internal rotation refers to the over rotation of the foot, or the rotation of the foot when it is not supposed to rotate, for example, the late stage of the whole palm in the gait cycle.

At this point, the inner side of the foot will bear too much weight. When the runner advances, the load will be borne by the inner edge, not the front foot.

This can lead to instability of the feet, which will not only affect the efficiency of running, but also cause obstacles to running.

Runners with excessive internal rotation should consider running shoes with high supporting functions, providing enough rigidity for the inner side of the arch, and effectively improving the stability of the feet.

On the Internet, the way of judging the movement of the sole of the foot is often based on the arch of the foot. It can only be said that this is a general situation, and there are runners who are low arch but lack of internal rotation, or high arch but excessive internal rotation.

The actual situation is still judged by the wear of the sole or the movement of the running feet on the treadmill by professionals.

Running is a dynamic behavior. Don't talk on paper, choose shoes on the sole of your feet. In addition, Neutral (cushioning), stability (Stability, Structural Cushioning), motion control (Motional control) and other shoes classification or address each shoe factory slightly different, shoes should pay special attention to, can first browse to each shoe factory website, record the correct classification and try again.

With the change of running experience and physical quality, weight and movement of the sole can be changed. Every time we choose shoes, we should judge the basis of the recent wearing shoes and the feeling of running. We should make adjustments at any time, try different kinds of shoes, get the best protection for both feet, and also have the best running efficiency.
