The wavelength of light used in the headset has been carefully selected to optimally penetrate biological tissue. This wavelength of light is just barely visible to the human eye. Hair does absorb some of this light which is accounted for by the power of our LEDs, and the distance they are placed. We measure the effect on your individual brain and adapt to optimize for the desired outcome. This personalized and adaptive transcranial photobiomodulation (tPBM) is unique to Sens.ai. We use 810nm and the power is estimated at 296.8mW/cm2 per LED.
