CRUZ-RODRIGUEZ, Andrés M.  and  SANCHEZ-MACHET, Hernán. HAND PROSTHESIS CONTROLLED BY EEG SIGNALS. Momento [online]. 2021, n.63, pp.34-51.  Epub Aug 31, 2021. ISSN 0121-4470.  https://doi.org/10.15446/mo.n63.96407.

This work describes how brain waves produced in the left lateral lobe of the human brain and detected with a NeuroSky MindFlex headset were used to voluntarily control a prosthetic hand. In the first instance, the EEG (electroencephalographic) signals are detected by a BCI (Brain Control Interface) and after being analyzed with the help of an ARDUINO microcontroller, their frequency spectrum is divided into Alpha, Beta, Theta and Gamma ranges. As a result of the EEG analysis, it is found that voluntary blinking affects mainly the power values related to the alpha band, such that this frequency band is finally used to direct in a voluntary and controlled way the abduction and adduction movements of the fingers of the prosthesis.

Keywords : Prosthesis; brain signals; brain interface; ARPUINO.
