Muse 2 EEG headband

Muse is a smart headband that acts as your personal meditation coach. Using advanced EEG brain sensors, Muse can detect your brain activity and provide you with real-time feedback in the form of gentle audio sounds through your headphones (regular use in the Muse app). Primarily advertised as a neurofeedback tool, the headband tracks heart rate (PPG + Pulse Oximetry), angular velocity (gyroscope), proper acceleration (accelerometer), and electroencephalography (dry electrodes) to assist you in your meditation sessions.

The Muse can be connected to your computer using Petal Metrics: https://petal.tech/downloads This tool allows you to send the EEG data to your computer through OSC.   Update 2024: this app is no longer free

Brain waves are measured in hertz (Hz), which refers to cycles per second.
