The chair has a system with center of gravity that is maintained constantly, that is to say that the person is kept standing naturally,” explains the electronics engineerAntonio Álvarez Abril, one of the teachers in charge of the project.The specialist explains that, when people stop, our center of gravity makes the stop smooth and not abrupt . That's what this inventionimitates, which differs from the rest of the artifacts that keep people standing like a board, firm.

On the other hand, it is important to note that the chair is even suitable for paraplegic people, with almost no mobility. Through electroencelography signals, with a simple flicker, the person can give orders and choose a certain angle of displacement for the chair.

The project worked together teachers and fellows from the Regional Institute of Bioengineering (IRB), dependent on the UTN, and also included the participation of the engineer Nelson Dugarte Jerez and students from the University of Los Andes (Venezuela).
