The students of the Celaya Institute of Technology, Eber Gardu\u00f1o L\u00f3pez, Mariel Sara\u00ed Garc\u00eda Hern\u00e1ndez and Oscar Cantera Cantera won in the area of &#8220;Public Health&#8221;.<\/p>\n<p>The <strong>prototype only works in a state of deep concentration<\/strong>. According with Gardu\u00f1o Lopez, the <strong>patient needs to be relaxed and concentrated to be able to generate a continuous movement in the wheelchair<\/strong>. So, he explained, the <strong>user needs training and practice to use the headband, because it is like a muscle, exercising would help you reach more advance levels<\/strong>.<\/p>\n<p>According to the young scientists, the challenge is to make as affordable as possible, since electric chairs controlled by (joystick) cost about 35,000 thousand pesos (US$ &nbsp;1,636) and chair controlled with the mind are not yet commercialized.<\/p>\n<p>&#8220;<strong><em>At the beginning of the research project, which took more than a year, it was thought to use a headband of electrodes with a cost of around 16,000 pesos. When we realized the price was still too high, we did some improvements and obtain a new headband that would have a cost of 2,500 pesos, which would represent a significant improvement, since the cost of the wheelchair would be reduced to less than a half, and more people would have enough resources to acquire it<\/em><\/strong>,&#8221; said Cantera Cantera.<\/p>\n<p>The students will present their innovation as their final project to receive their degrees. However, they plan to continue working in the project; and they will invest the prize of 50,000 pesos to improve their innovation.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Source: <\/strong><em>Agencia ID<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Students of the Technological Institute of Celaya developed a wheelchair that can be directed by electrical brain signals.
