Wrist-worn Optical Heart Rate Monitoring: a Comprehensive System Approach

Abstract

Optical heart rate monitoring has become a commodity in today's smartwatches with a limited measurement precision and reliability, especially during the presence of motion. Expertise in physiology, optical skin interface, electronics, mechanics, industrial design, and signal processing are essential to achieve high accuracy. CSEM solution has demonstrated excellent performance not only for heart rate (HR) monitoring during outdoor activities and exercising, but also for RR interval detection, heart rate variability analysis, perfusion, sleep analysis, and speed assessment.
