Abstract
An apparatus for non-invasively measuring bio-information is provided. The apparatus for estimating bio-information may include a pulse wave sensor configured to measure a pulse wave signal from an object; a sensor position sensor configured to obtain sensor position information of the pulse wave sensor with respect to the object, based on the object being in contact with the pulse wave sensor; and a processor configured to estimate the bio-information based on blood vessel position information of the object, the sensor position information, and the pulse wave signal.
Claims21
An apparatus for estimating bio-information, the apparatus comprising:
- a pulse wave sensor configured to measure a pulse wave signal from an object;
- a sensor position sensor configured to obtain sensor position information of the pulse wave sensor with respect to the object, based on the object being in contact with the pulse wave sensor;
- and
- a processor configured to estimate the bio-information based on blood vessel position information of the object, the sensor position information, and the pulse wave signal.
A method of estimating bio-information, the method comprising:
- based on an object being in contact with a pulse wave sensor, obtaining sensor position information of the pulse wave sensor with respect to the object;
- driving the pulse wave sensor to measure a pulse wave signal from the object;
- and
- estimating the bio-information based on blood vessel position information of the object, the sensor position information, and the pulse wave signal.
An apparatus for estimating bio-information of a user, the apparatus comprising:
- a pulse wave sensor configured to measure a pulse wave signal from an object of the user;
- and
- a processor configured to:
- obtain sensor position information that identifies a position of the pulse wave sensor with respect to the object of the user;
- obtain blood vessel position information that identifies a position of a blood vessel of the object of the user;
- and
- estimate the bio-information of the user based on the pulse wave signal, the sensor position information, and the blood vessel position information.
