dc.description.abstractPhotoplethysmography (PPG) is becoming the standard technology for heart rate measurements in wearables because of its ease of use. Nowadays, numerous commercial off-the-shelf (COTS) analog front end (AFE) components dedicated to PPG are available. However, in everyday use cases, insufficient ambient light rejection (ALR) leads to poor AFE performances and subsequent inaccurate heart rate estimations. The results of a novel approach that solves ALR issues in daily life use cases are presented herein. CSEM has been active in the domain of PPG sensing and processing for more than 15 years, covering R&D activities ranging from optical design, AFE development, and embedded algorithms to application-specific integrated circuit (ASIC) implementation.
