ABSTRACT
In this paper, a design of the portable acquisition system for autonomic nervous function data based on the microcontroller is introduced. The system contains an electrocardiogram amplifier and an AD convertor, using SD memory card as its storage device and thus it can record data for a longer time and exchange data with PC easily. The system with a simple structure realizes its miniaturization and low energy consumption.
