Wearable device with physiological parameters monitoring

This invention is about a wearable device, like a smartwatch or fitness tracker, that uses light to measure your body's vital signs. It works by having a sensor with a central point, where two groups of tiny lights shine into your skin, and multiple detectors around them pick up the reflected light. This allows it to monitor things like your pulse. The claims specifically describe a version where a very thin physical barrier separates the two groups of lights.
