Low-power and Portable Design of Bioelectrical Impedance Measurement System

Abstract

This paper presents design principles of a low-power and portable bioelectrical impedance analyzer. Based on the low-power and portable notion, It uses a low-power computer as the core, adopting MSP430F149 chip as the processor and utilizing AD5933 which is launched by Analog Devices and is highly integrated to measure and collect the multi-frequency impedance information. And then these data will be sent to the control system on PC through its own serial interface, displayed in the man-machine interactive interface on PC.
