Wireless EEG Headband Makes You Look Like Nerdy She-Ra

Electroencephalography (EEG) is a method for monitoring brainwaves, traditionally assiociated with big, immobile medical machinery. IMEC has developed a wireless head-mounted EEG strap powered by the wearer’s own forehead heat. "At room temperature, the generated power is about 2-2.5mW or 0.03mW/cm2 which is the theoretical limit of power generation on human skin. Higher power generation […]

Electroencephalography (EEG) is a method for monitoring brainwaves, traditionally assiociated with big, immobile medical machinery. IMEC has developed a wireless head-mounted EEG strap powered by the wearer's own forehead heat.

"At room temperature, the generated power is about 2-2.5mW or 0.03mW/cm2
which is the theoretical limit of power generation on human skin.
Higher power generation would cause an uncomfortable sense of cold."

The system, which it sternly reminds everyone is proprietary, operates "completely autonomously and maintenance-free" and doesn't need batteries. A mere 0.8mW is all the current it requires to both read brains and send the data to a PC via 2.4Ghz.
