Wearable electronic device

This invention describes a wearable electronic device, like a smartwatch, that can tell time and monitor a user's health. It specifically includes a watch band, a display, and a rear cover with an optical sensor (photoplethysmography) and three electrodes for an electrocardiograph. The device is designed to measure changes in light absorption from the skin to calculate and display the user's respiration rate.

Why it matters: The claims detail computing respiration rate from light absorption. Advances in AI-driven signal processing and miniaturization since 2022 could now make this specific feature more accurate and power-efficient.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedIntegrated physiological sensors, custom electronics, signal processing
