This is a health monitoring watch that measures physiological parameters, like oxygen levels, using an optical sensor worn on the wrist. The sensor is designed with a curved surface to press against the skin for better readings and includes internal barriers to block stray light, making the measurements more accurate.
Why it matters: Advances in micro-fabrication and optical sensor integration since 2021 could make the specific convex curvature and internal light barriers more feasible and cost-effective to implement for improved signal quality.
