A wearable & flexible multi-channel fNIRS device for baby brain oxygenation measurement
*Hyperscanning not yet possible with iMotions Lab. Contact for more information.
The BabyBrite system is designed to provide high-comfort to young infants. We aimed to achieve this by using flat optode tips and soft optode holders, which are crafted from biocompatible materials, for extra safe and gentle skin contact on babies.
The soft-click principle allows an easy & fast setup. Additionally, this principle allows to easily move hair aside when infants have lots of hair.
The BabyBrite is an optimized version of the new Brite MKII for infant research, making use of similar improved technology. This device allows researchers the flexibility to conduct studies in many research settings. The flexible template feature enables researchers to measure brain activity from any location on the infant head. The BabyBrite package comes with distance guards that ensure stable inter-optode distance and mounting solutions for lab and real-life interactions (e.g. car seat; parent lap, high chair, crawling around).
The BabyBrite only weighs 300 grams, which makes it ideal for babies that are freely moving or asleep. You can set up your research wherever you want whenever you want!
