Development of a hardware-software measurement system for the collection, detection, and processing of photoplethysmograms

摘要

A photoplethysmograph with a data acquisition circuit board, using a USB interface and an analog optical sensor, was developed. This study describes an information system for collecting, processing, and storing photoplethysmographic pulse curves. Using a photoplethysmograph, a small sample was collected for processing using a software package written in the MATLAB programming environment. (C) 2020 Optical Society of America
