The forefront of wearable fNIRS devices

  • Measures oxy-, deoxy- and total hemoglobin concentration changes from any cortical brain areas.
  • The multi-power gain control allows one to select, automatically or manually, the optimal optical settings for each brain area and participant.
  • Flexible inter-optode distances to measure short and long channels.
  • Integrated 3-axis accelerometer and 3-axis gyroscope to measure movement data.
  • Compatible with other techniques such as EEG and tES.
  • Easy data acquisition and analysis with our superior software solutions, OxySoft and Brite Connect.
  • Record with a high sample rate using Bluetooth or Wifi, or record offline.
  • Elevated flexibility with the MultiBrite configuration.

Wearable…anywhere & for everyone!

The Brite MKIV is a state-of-the-art, wearable, and flexible multi-channel fNIRS device designed for advanced brain oxygenation research. Weighing just 300 grams, this ultra-light system can be easily attached to the Artinis fNIRS headcap, offering unmatched portability and comfort for diverse participants, including children and elderly individuals. Combined with offline data storage, the Brite is ideal for studies in any environment—labs, clinics, or even outdoors.

Equipped with advanced multi-wavelength light transmitters, the Brite MKIV provides continuous, real-time data seamlessly integrated into our user-friendly analysis software. Its innovative multi-power gain control includes four power levels and auto-power settings, ensuring optimal data quality across various skin tones, hair types, ages, and cortical distances. Including sensors with high sensitivity, setup is now easier and quicker, especially when measuring over hair.
