The objective of this study is to design a coaxial sensor for the dielectric measurement of
biological tissues below 100 MHz with reasonable uncertainty. To do this, the dimensions of
the coaxial sensor were determined by estimating the measurement uncertainty on the basis
of sensitivity analysis and adopting the specifications of the measurement equipment as the
sources of uncertainty. A fabricated sensor was used for the dielectric measurement of

Abstract
The objective of this study is to design a coaxial sensor for the dielectric measurement of biological tissues below 100 MHz with reasonable uncertainty. To do this, the dimensions of the coaxial sensor were determined by estimating the measurement uncertainty on the basis of sensitivity analysis and adopting the specifications of the measurement equipment as the sources of uncertainty. A fabricated sensor was used for the dielectric measurement of porcine muscle, and the results of the uncertainty analysis demonstrated that the measurement can be conducted within a standard uncertainty of 1% from 1 to 100 MHz.
