Technology

All of the devices listed use electroencephalography except the Neural Impulse Actuator which only uses electromyography. Some use both electroencephalography and electromyography, such as the BrainBand MindWave, EPOC, and MindSet.

The OpenBCI board can acquire electroencephalography (EEG, electrical activity of the brain), as well as electromyography (EMG, electrical activity of skeletal muscles), and electrocardiography (ECG or EKG, electrical activity of the heart) data.
