WEARABLE OPTICAL PULSE PLETHYSMOGRAPHY SENSORS OR PULSE OXIMETRY SENSORS BASED WEARABLE HEART RATE MONITORING SYSTEMS

摘要

A new PPG/SpO2 based ear hook sensor was constructed with the PPG/SpO2 sensors are attached to the skin in the regions of superficial artery and vein (010) and posterior auricular artery and vein around the ear (011 of FIG. 1C). An ear wearable heart rate monitor is constructed with PPG/SpO2 sensors are attached to the skin in the regions of superficial artery and vein (010) and posterior auricular artery and vein around the ear (011 of FIG. 1C) (temporal region of the head). This sensor system is less vulnerable to motion artifacts hence capable of producing high quality PPG signals under motion conditions such as running and exercising.
