16-channel EEG

16 electrodes strategically placed to provide optimum coverage of the brain and to capture all the signals.

NExstem Headset features

Frontal Lobe
Primary Motor Cortex
Somatosensory Cortex
Parietal Lobe
Frontal Lobe (AF3, AF4, FZ) captures signals related to human cognitive skills.
Parietal Lobe (CP3, CP4, CPZ, PZ, PO3, PO4) - captures signals related to sensory information reaching the brain from external factors like taste, touch, etc.
Primary Motor Cortex (FC3, FC4) - captures signals related to movements
Somatosensory Cortex (C3, C4, C5, C6, CZ) - captures signals related to sensory information reaching the brain from the entire body

Polymer Ag Electrodes

Polymer Ag/AgCl electrodes are industry-standard non-polarizable electrodes used in EEG-based clinical measurements. These electrodes are popular for low electrode-skin impedance and low noise. A 15-pin dry EEG electrode is easy to use and comfortable to wear.

Active Electrode system

Active Electrode System integrates an amplifier with high input impedance, low noise and good electrode offset rejection. It locally amplifies and buffers μV-level EEG signals before driving any cabling, leading to lower noise levels compared to conventional passive electrodes

Buffered Signal

Unbuffered Signal

Connectivity modes

Connects via Bluetooth 5.0 and also via Wi-fi to ensure low latency and fast data transmission. The headset is also preconfigured to connect to the SDK hosted on Microsoft Azure.

Wisdom SDK

Bring the most out of your NexStem headset, with the Wisdom SDK. Create customised BCI applications and devices.
