Abstract
Impedance measurements are gaining importance in wide field of research. This paper presents the design and construction of an impedance measurement device based on the AD5933 integrated circuit. Our low-cost system can be used in many areas of bioresearch. For the purpose of this paper, the device was used as impedance cardiography (ICG) analyzer for human thoracic impedance measurements. The measured raw data from impedance recordings were processed in order to extract specific features and several important hemodynamic parameters were calculated from the ICG curve.
