Hero

Wearable EEG engineered for advanced cognitive and sensorimotor research.

Lightweight, wearable dry-EEG with an integrated amplifier, designed to facilitate user mobility. Developed for advanced research in cognition and motor neurorehabilitation in natural environments. Wireless connectivity and optional data storage on a microSD card.

What is included

Hero EEG

Its lightweight (250 g) and flexible design adapts to any cranial morphology. It features 9 dry sensors covering fronto-central, central, and centro-parietal areas, plus one linked-ear reference.
The device ensures high signal quality and an enhanced SNR through active shielding and DRL. The integrated amplifier includes motion tracking, Bluetooth transmission, and microSD card backup storage.
