Digital Sensors and Sensor Sysstems


Abstract: While entering the modern society, medical technology has been able to cure almost all kinds of diseases. However, autoimmune diseases are increasing rapidly due to environment, food, and indoor life. In particular, vitamin D is lacking in about 90 % of Koreans. As a result of this, many middle-aged and older women are taking calcium, but most of them do not know their vitamin D levels. Based on this background, the goal of this paper is to develop a vitamin D measurement technique using a quantum analyzer that is capable of measuring various kinds of vitamins and minerals, and to prepare a plan to easily measure vitamin D by attaching it to a UVB device that is currently used in the hospital. The quantum analyzer was designed based on the impedance principle, and the impedance change according to vitamin D concentration was able to confirm a significant proportional relationship between vitamin D and impedance. In addition, the correlation between vitamin D and impedance was confirmed by in vitro experiment using lab mice, and the measurement error of the impedance meter for vitamin D concentration in the blood was confirmed to be about 12.7 %.
