Abstract
Conference Title: 2018 IEEE Biomedical Circuits and Systems Conference (BioCAS) Conference Start Date: 2018, Oct. 17 Conference End Date: 2018, Oct. 19 Conference Location: Cleveland, OH, USA Tissue mimicking materials are used as a safe alternative testing platform during the development of medical applications such as wearables devices and body area networks. Identifying the accurate electrical properties of the materials in use is important to guarantee accuracy and reproducibility of results. In this paper, we propose a novel extraction technique for the Cole-Cole model of tissue-mimicking materials. The proposed method is based on optimizing the relative error for both real and imaginary parts of the complex permittivity of the fabricated materials. Extracting the model is helpful to study the effect of changing materials percentages to fit the real human body tissues. The proposed technique, when applied to in-house developed tissue-mimicking materials, showed a good match with relative error less than 5% in both permittivity parts.
