Uses infrared light sensing to determine changes in blood oxygen levels in the brain in real time. Use the device in less than ten minutes to learn how to directly change blood flow to your brain. Neurons do not store energy, so regional brain activity is closely related to changes in blood oxygenation, where healthy blood flow patterns are essential for high function and growth of the brain.
Reliable health monitoring has traditionally required us to tether ourselves to machines that record our vital signs around the clock. However, outside of clinical settings this is rarely practical. We developed HealthyPi v4 in part to address this challenge. Building on its predecessor, HealthyPi v4 is a fully open source standalone vital signs monitor with wireless and wearable capabilities.
