“Was like a beach...just looking at them, the rocks...I can see my feet...I had a small image of running in a field. And then feeling the grass hit on my feet.”
Masca is a low-cost, flexible mask for sleep stage detection. Our device adapts to the human body using conformable piezoresistive fabric and silicone, enabling eyelid motion detection in a comfortable, affordable form factor. Eyes and eyelids change movement frequency predictably as sleep stage transitions occur, allowing for a simpler, more portable system than the typical high-density EEG required for sleep tracking. Tracking and influencing of sleep cognition opens up doors to targeted reactivation of daytime experience during sleep: a future in which the consolidation of emotion, memory, and learning in sleep is rendered controllable by wearable electronics.
