ABSTRACT
Bio-Electrical’Impedance(BEI), Electroencephalogram(EEG) and Electrocardiogram(ECG)signals that are biologically important three types of electrical signals,which can provide a reference for monitoring the health of the biological health parameters of traditional measurement method is mostly measured by large medical instruments,although the accuracy is higher, but the operation plex,professional and strong,cost measurement of high disadvantage hinders the of these instruments to further promote and popularize. Therefore,it is necessary to design portable biological signal measuring system.
Based on the previous work,this paper designs,makes and tests the
portable multi parameter biological signal measurement system,and pletes the following work:
paper present situation of development on the bioelectrical impedance,
EEG and ECG system design and applications at home and abroad to make certain hardware are introduced and proposed framework for portable multi—parameter biological information measurement system.
paper introduce the advantages and disadvantages of the relevant
components,determine the core of portable multi-parameter biological information measurement system(module)chip and platform,Among them,the electric impedance measurement module,the ECG signal measurement module
and the EEG signal measurement module are AD5 93 3,BMD 1 0 1,TGAM, respectively,and Bluetooth wireless transceiver module BLK-MD—BC04一B, total control platform using embedded data processing pl
