Elektrolitlerde ve Biyolojik Materyalde Lokal Özdirenç ve Mobilite Değişim Oranı Tayini
Abstract
This study introduces a novel dipole electrode technique developed to investigate the electrical characteristics of electrolytes and biological tissues. By manipulating electrode geometry and applying high-frequency sinusoidal voltage, local specific resistivity values can be accurately measured, enabling the assessment of biomedical parameters such as sedimentation rate and hematocrit levels. Additionally, mobility variation ratio measurement reveals insights into ion movement and fluid viscosity. The system provides reliable data through rapid assessments, offering valuable advantages in examining biological materials.
