Title:
MEASUREMENT DEVICE AND MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2024/070653
Kind Code:
A1
Abstract:
The present technology pertains to a measurement device and a measurement method which enable accurate measurement of the concentration of glucose (dextrose) contained in an object to be measured. The concentration of glucose in the object to be measured is calculated on the basis of the complex dielectric constant of the object to be measured and moisture content of the object to be measured. The moisture content can be calculated on the basis of an incident signal, which represents an electromagnetic wave incident on the object to be measured, and a reflection signal, which represents reflection by the object to be measured.
