description: The given work is devoted to development of a medical sensor for measurement of liver's function and evaluation of its sensitivity. Liver's function is measured by tracking a kinetics of a decrease in blood's colored component concentration using an optical method. Task of this work are:1. Analysis of literature and selection of photometric method of concentration measurement.2. Specification of principles by which the sensor functions and testing scheme description.3. Experimental study of the sensor's optoelectronic components main characteristics.4. Calibrating curve composition, experimental definition of the sensor's sensitivity threshold and resolution.In this work were used methods of an absorption analysis and a calibration curve method. Results of this work are:1. The method of a calibration curve was chosen.2. Given description of the scheme of software and hardware sensor's components, specified requirements for parts of the sensor.3. Experimentally acquired parameters of sensor's optoelectronic components which allow optimization of sensor's design.4. Experimentally acquired the calibration curve, based on it the sensor's threshold sensitivity and resolution are evaluated.Collected data allow sensor's design optimization and give information about reliability of data acquired by the sensor, this, in turn, allow more correct assumptions about liver's condition.
