BitBrain Ring

  • Functionality: The Ring is a wearable biosignal device designed to monitor electrodermal activity (EDA), also known as galvanic skin response (GSR), and blood volume pressure (BVP). These are used to analyze physiological responses related to emotional and cognitive states.
  • Sensors:
    • EDA for skin conductance.
    • BVP for cardiovascular activity.
    • 3-axis accelerometer to mitigate movement artifacts from finger motions.
  • Sampling Rate: 32 samples per second with 16-bit resolution.
  • Connectivity: Bluetooth 2.1 + EDR for wireless data transmission up to 10 meters. Data can also be stored on a microSD card (up to 8 GB).
  • Battery Life: Provides 10+ hours of continuous use with a rechargeable battery that fully charges in 3.5 hours.
  • Weight: Extremely lightweight at 60 grams.
  • Applications: Ideal for real-world scenarios where quick, non-invasive monitoring of emotional and cognitive states is needed, such as in psychology studies or behavior research​.

BitBrain Diadem

  • Functionality: The Diadem is a dry-EEG headset that monitors brain activity using 12 electrodes positioned over specific brain regions to estimate cognitive and emotional states. It is used for applications like brain-computer interfaces (BCI), neurofeedback, and human behavior research.
  • Sensors:
    • 12 dry-EEG sensors (Fp1, Fp2, AF7, AF8, F3, F4, P3, P4, PO7, PO8, O1, O2).
    • Integrated IMU (9 axis): Accelerometer, gyroscope, and magnetometer.
  • Sampling Rate: EEG data is recorded at 256 samples per second, with a 24-bit resolution.
  • Connectivity: Bluetooth 2.1 + EDR for data streaming within a 10-meter range, and microSD storage for data backup (up to 8 GB).
  • Battery Life: 8+ hours of continuous recording with a rechargeable battery that charges in less than 3 hours.
  • Weight: 185 grams for the headset, with an additional 125 grams for the amplifier.
  • Applications: Suitable for real-world EEG studies, wearable neuroscience applications, and neurotechnology development.

These devices are designed for versatile applications in research and real-world settings, offering powerful tools for monitoring human physiological and neurological signals.
