Heart rate measurement and electrical pulse signal analysis for subjects span of 20–80 years

摘要

Highlights ? We provide heartbeat prototype for supporting the preliminary medical science. ? We study the heartbeat and pulse signal that are used with hardware and software. ? Heartbeat data can be recorded into memory card. ? The optical finger sensor is detected with real time measuring. ? Prototype can be used in clinical lab, with 95% accuracy, and cheaper price. Abstract The preliminary research constructs the heart beat or pulse measurement for medical science. The electrical pulse signal analysis that supports one significant clinical study. The research prototype focuses the pulse rate and analysis system which consist of hardware and software parts. The hardware uses the ATMEGA 2560 ADK R3 for processing the input optical sensors, output result to LCD, and record data into SD memory card. The software as embedded algorithm is designed for controlling the input/output parts. Research techniques are applied in term of analog to digital converter, I2C, and data grouping. The 40 subjects are informed consent and measured with ethical research. Experimental result explains the subject behaviors with maximum/minimum pulse values, patterns, and similarity three groups. The distinctive point of medical and health science prototype is accuracy, durability, low power consumption, and cheaper price.
