Abstract
An apparatus for estimating blood pressure includes: a sensor, and a processor configured to estimate blood pressure based on a PPG signal and a contact pressure signal measured by the sensor. The sensor includes: a transparent elastic body; a first polarizing film provided on a surface of the transparent elastic body and configured to come into contact with the object; a light source provided under the transparent elastic body and configured to emit light toward the object; a first detector and a second detector provided under the transparent elastic body and configured to detect light, passing through the first polarizing film after being emitted by the light source and scattered or reflected from the object, to measure the PPG signal; and a second detector provided under the transparent elastic body and configured to detect light, not passing through the first polarizing film, to measure the contact pressure signal.
