In this work, an attempt has been made to correlate the dielectric permittivity of polyacrylamide based tissue mimicking phantoms with their mechanical properties such as breaking stress, breaking strain and Young's modulus. The tissue mimicking phantoms of various concentrations were prepared as per the standard protocol and their permittivity was measured using a precision impedance analyzer. The mechanical properties of the phantoms were measured by conducting tensile tests using a Universal Testing Machine. The measured mechanical properties were correlated with the dielectric permittivity by performing statistical analysis. Results demonstrate that the percentage variation in the mechanical properties correlate well with the percentage variation in the permittivity of the tissue mimicking phantoms. Further, it appears that the changes in the mechanical properties of the phantoms can be estimated by quantifying the changes in their dielectric permittivity. In this paper, the objectives of the study, methodology and significant observations are discussed in detail. © 2010 World Scientific Publishing Company.
