Spettrometro e pletismografo di impedenza per applicazioni diagnostiche e di monitoraggio
In this paper, the design and characterization of a device, able to analyze the electrical bio-impedance in the frequency domain and its variations with time, is presented. The whole system design, that employs a tetra-polar electrode configuration, a specifically developed printed circuit board, and a data acquisition card connected to a PC, is presented. The measurement system is controlled through LabVIEW virtual instruments.
