Scientists at two universities in Atlanta, Georgia, in the southeastern United States, have just invented a device that makes going up and down stairs easier.

This information was recently published in the Public Library of Science Plos One journal. Accordingly, scientists have invented a spring-loaded device, attached to the steps, to help regenerate strength for people using stairs.

By using this device, users will save 26% of the energy consumed by the impact force and braking force of the ankle, every time they go down the stairs and release 37% of the knee energy when going up the stairs.

The release of energy is achieved through spring-loaded steps and pressure sensors, mounted on the device. When a person steps down a stair, the step will be lowered slowly, until it is level with the lower step, saving energy for the user.

This cycle will continue until someone steps on the ladder. The ladder user steps on a sensor device installed on the upper steps, the locking hook of the lower step is released, creating a push force, acting on the user's remaining foot, helping the user to lift his foot up more easily.

According to scientific researchers, this device can be easily removed and installed on different types of stairs, at a relatively low cost.

For buildings without elevators or escalators, especially in multi-storey apartments, it will be a useful solution for some cases that require mobility support for a certain period of time, such as patients recovering from surgery or pregnant women.
