Heart rate monitoring system in a headset for stress detection
A recently granted patent (Publication Number: US11980464B2) discloses a system designed to determine heart rate data of a user through a headset for voice communication. The headset, worn at least partly in the ear, includes a voice communication unit, speaker, microphone, and a photoplethysmograph (PPG) sensor for optically measuring the user's heart rate through the skin. A processing unit connected to the PPG sensor calculates heart rate data based on sensor measurements, detecting whether the user is on-call or off-call. The system also analyzes beat-to-beat intervals to determine heart rate variability, low and high-frequency components, and stress levels based on ratios of these components during different time intervals.
Furthermore, the system includes a notification unit to alert the user of any heart rate increases, a motion sensor to filter out motion-induced artifacts, and ensures the PPG sensor is positioned close to the skin surface for accurate readings. The PPG sensor can be mounted in the earphone housing or ear cushion, with a protrusion designed to rest at the preauricular skin pit area for optimal placement. Additionally, a fixation part is included to secure the earphone housing in place, ensuring the PPG sensor remains positioned correctly during use. Overall, the system offers a comprehensive solution for monitoring heart rate data in real-time through a headset, providing valuable insights into the user's cardiovascular health and stress levels.
