Study on measuring cholesterol level using microwaves

The glucose and cholesterol level is indicated as value of vital signs. To check these levels, invasive measurement is necessary to obtain blood sample and cause a pain of the body as heavy burden to the patient. In this paper, reflection method which is applied for noninvasive microwave measurement for cholesterol is studied using microwares. The cholesterol was dissolved in ethanol and make cholesterol solution. Relative permittivity and dielectric loss have measured and evaluated. Regression line is made to simplify the relation between the relative permittivity and dielectric loss versus cholesterol concentration, it become clear.
