Abstract: A health monitoring system includes a band that is wearable on a user's extremity, such as a finger. A pulse oximetry sensor is disposed at an inner surface of the band and is configured to collect data representative of the heart rate and blood oxygen level of the user. An electronic control unit (ECU) is connected to the pulse oximetry sensor. When the band is worn by the user, the pulse oximetry sensor collects heart rate and blood oxygen level data and transmits the collected data to the ECU. The ECU receives the collected data from the pulse oximetry sensor, processes the collected data, and stores the processed data at a time interval, such as every 3 seconds or less. When the band is removed from the user, the ECU transmits the processed data stored in the storage unit to a remote device.
