RESUMO
This paper presents the construction of a probe for immittance spectroscopy. The probe is based on the four-electrode technique. The current application electrodes are long parallel strips and have been partitioned into three segments to measure the immittance of relatively small volumes. The probe constant has been calculated assuming anisotropy of the materials examined. The experiments, based on the measurements of KCl solutions and numerical simulations (finite element method--FEM), have shown a high degree of consistency with the theoretical value. Experimental in vivo measurements on swine gluteal tissue were performed and the conductivity and permittivity reconstructed from these measurements are presented.
