I have been working with a friend on a BMI project since december 2019. We are true believers in the near revolution of brain machine interfaces (BMI) but BMIs available today are either invasive, constraining or awkward (in particular EEGs), and we believe surface EMG is the way to go. Although electromyography is an old technology, its potential for BMI has not been realized until recently and interest is growing. So we built an armband which possesses electrodes that are held in contact with the user’s skin. The electrodes, combined with a specialized acquisition/processing hardware, intercept and measure electrical signals propagating in the muscles when the user intends to move his/her hand (with or without actual movement). The processed data is transmitted via bluetooth to the device that the user wishes to control, and translated there into actual commands (moving a cursor, typing text, etc...). Please see our video !
