Your body uses glucose to provide energy for all your cells. As glucose levels change in your body, so does your body’s ability to move. This affects the way your heart pumps and the way that your arms and legs move.
Smart watches have sensors that can monitor your movement and the way your heart beats.
Photoplethysmography (PPG)
A fancy word for the LED that shines light into your skin. As blood flows by, oxygen reaches the cells in your skin and changes the way the LED light reflects back. This corresponds to how your heart beats. This image shows what the raw signal looks like from the PPG sensor.
Accelerometer
As you move your arm around, the accelerometer measures the acceleration of your wrist. Acceleration has three different directions: up/down, left/right and backwards/forwards. This image shows what raw accelerometer data looks like:
Gyroscope
As you rotate your hand and arm, the orientation of the gyroscope changes. This is similar to yaw, pitch and roll in an airplane and gives an additional three variables that characterize how you move your arm.
Learning from the Raw Data
The graphs above show the raw data coming from your smart watch. We perform a series of 14 layered, mathematical algorithms and transforms to turn these waveforms into more than 100 features that describe your unique heart rate and motion.
These features are coupled with cutting-edge artificial intelligence to find out how your motion and heartbeat correlate to your blood glucose. We create a model of your blood glucose just for you. Instead of trying a one-size-fits-all approach to the billions of unique individuals in the world, we decided to just treat each person as an individual and learn their personal profile.
