The photoplethysmographic (PPG) signal is an important source of information for estimating heart rate (HR). However, the PPG signal could be strongly contaminated by the motion artifact of the subjects, making HR estimation a particularly difficult problem. In this paper, we propose PARHELIA, a PARticle filter-based algorithm for HEart rate estimation using photopLethysmographIc signAls. The proposed...
Our group has proposed and demonstrated a silicon-based guided-wave optical accelerometer with a proof mass centered on a diaphragm. It is strongly suggested that sensitivity is related to many factors, such as waveguide position, diaphragm dimensions, and size and weight of proof mass. These relationships need to be clearly identified in order to establish a design guideline. In this study, sensitivity...
