"Fitbit's Potential Breakthrough: Arterial Stiffness Monitoring Patent Unveiled"

Fitbit has filed a patent for heart health monitoring technology that utilizes PPG (photoplethysmography) to measure arterial stiffness. The patent includes a new wearable fixing structure, inertial sensor, PPG sensor, and CPUs, with the intention of optimizing the PPG sensor for various scenarios such as exercise, sleep, and work. Fitbit may also include additional sensors like temperature, strain, and stress to improve accuracy. If successful, this technology could enhance Fitbit's wellness capabilities and potentially be integrated into future devices like the Versa, Sense, and Google's Pixel Watch.
