Abstract

An apparatus noninvasively measures blood sugar concentration. The apparatus includes: a tissue modulation unit applying a pressure to a tissue; a hemoglobin (Hb) concentration measurement unit analyzing an amount of absorption of electromagnetic waves on a first portion of the tissue before and after the applying of the pressure by the tissue modulation unit, and measuring Hb concentration of the tissue; and a photoacoustic module unit analyzing photoacoustic signals to measure blood sugar concentration, and correcting the measured blood sugar concentration based on the measured Hb concentration to output a final blood sugar level, the photoacoustic signals being created from the tissue by emitting a pulse laser ray towards a second portion of the tissue before and after the applying of the pressure by the tissue modulation unit.
