Walking will become easier and more efficient now, thanks to a battery-less device which was developed by engineers. The prototype exoskeleton boot, when worn, has the capability to reduce the energy that is required to walk, by 7 percent. It runs from the ankle up to the knee. As the energy is reduced, you will burn a lot less calorie. This wearable can be the perfect solution for those who have difficulty walking. The feature which makes this boot different than the others is that it does not need any battery or power source to run. So, how does it work? Let us find out from this post.

Power-Less Wearable Robotics

This boot is a wearable robotics without any power source or motor. It weighs only one-pound. The device depends on a spring to store energy and with each step that the wearer takes, the energy is released. The spring is engaged at the correct time with the help of a clutch.

The device however, is a bit bulky and won’t fit under your socks or pants.

Steven Collins, an engineering professor at the Carnegie Mellon University and the lead author of a study which was published in the journal Nature, said “It doesn’t look too bad. Looks kind of flashy.” When you first put them on, it feels a little bit odd, then after a few minutes you don’t really notice it very much.”

While this might not be a good idea for obese people, it could help people with disabilities to walk better. According to Collins, developing the clutch was a key innovation.

Studies have shown that when biking or running becomes tough, people tend to reduce it. Collins said that in the long run, people could walk more and burn more calories as it becomes easier.

Created as an Engineering Challenge

Collin said that the device won’t be marketed or manufactured by him, but others could take the initiative to do so. It was developed as an engineering challenge rather than a plan to create the next popular wearable. The challenge was to see if scientists could improve on nature without the use of motors.

Andy Ruina, a biomechanical engineering professor at the Cornell University said “Most studies show that human walking is incredibly efficient, so finding a way to make it better is incredibly interesting.”

Ruina and other engineers, who were not a part of the project, praised the new device.

Do you think this wearable booth could help wearers? Are you going to try out this boot if it is manufactured in the future? We would love to hear your views.
