Experimental Ankle Exoskeleton Increases Walking Speed ​​by 40%

As people age, they tend to walk more slowly. This is due to neuromuscular degeneration or general "wear and tear"

body. As a result, older people and people suffering from various diseases begin to walk much more slowly than they would like.

A team of scientists at Stanford aims to solve thisproblem. They are currently working on a concept for an electrically powered exoskeleton. In fact, it takes over some of the physical effort, allowing the wearer to move faster. Scientists plan to shrink the device to fit easily around the shin and inside the shoe. This will allow you to select your preferred walking speed.

Now the exoskeleton is an emulator.That is, this is an experimental setup. It is used on a treadmill where the exoskeleton is powered by a cable. It is connected to large external motors and controlled by an algorithm. When the wearer walks, the exoskeleton acts like a mechanical calf muscle. She applies a little force to each step, pulling her heel up and pressing her toes down. This increases the wearer's walking speed by approximately 40%. For developers, such high efficiency came as a surprise. Experiments showed that a 40% increase in speed is more than the difference between young and old people.

The immediate goal is to make the prototype moreefficient and comfortable. Ultimately, scientists are planning to create an exoskeleton that works on its own and can be worn by the elderly. This more advanced version will not only improve your walking speed, but will also help relieve pain from joint overload or imbalance.
