Climbing Stairs Just Got Easier with Energy-Recycling Steps

 Energy-Recycling Steps

Scientists make it easier to climb stairs with new age energy recycling steps

If you have trouble walking up and down stairs then researchers from Georgia Tech has a device meant just for you. They had been successful at making the world’s first energy recycling stairs which has the unique features of storing as well as returning the energy to the users while moving up and down the stairs. The working of this device is quite simple and right to the point which makes it easier for anyone to make use of it.

It has been found that this spring loaded stairs results in saving energy by 26 percent while going up or down the stairs. When some goes up using this device then it releases the stored energy and in the process it makes it 39 percent easier for the subject to move up the stairs. It also remains soft on the knees and seriously limits the amount of energy which is usually wasted while using the conventional stair cases. The best thing about this device is that it can be easily placed on the existing stairs without the need of even installing it permanently.

How this stairs works? 


The working of this energy recycling device has been defined by Karen Liu, an associate professor AT Georgia Tech. She explains that normal walking usually results dissipating energy with each heel strike which can be easily store and utilized in the ascent using this device. In order to achieve this functionality each stair is made up of springs which are equipped with pressure sensors. When a user walks downstairs the steps sinks and lock in a certain position which helps in storing the generated energy and when someone walks upstairs then this stored energy is released. Researchers are going to publish their findings in the journal called Public Library of Science PLOS ONE.

A simple idea with wider future application of Energy Recycling

 

The idea behind this device came to Liu when she attended a conference and got to see a unique ankle brace which effectively works on the basis on storing and releasing the energy. Secondly she also saw her 72 year old mother having grave walking difficulty and problems associated with climbing the steps. Thereon she got the idea of creating smart stairs rather than the sneakers.

Her device is extremely low cost which means wider number of people suffering from the knee and walking issues will be able to buy it. This energy recycling stairs can be easily installed in the home which isn’t possible when it comes to having stair lifts or elevators at home.

It is also believed that this device will allow users to maintain their mobility by allowing them to keep walking and moving around even through injury and it will eventually help in elevating the quality of life in the long run. When it comes to application this energy recycling stairs can act as the temporary stars at home, hospitals or old age homes where older people or people recovering from surgery are spending their time.
