Abstract
An apparatus for estimating 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 force sensor configured to measure a first force exerted between the object and the pulse wave sensor; and a processor configured to: convert the first force into a second force, based on structure information of the object; and estimate the bio-information, based on the pulse wave signal and the second force.
Claims28
An apparatus for estimating bio-information, the apparatus comprising:
- a pulse wave sensor configured to measure a pulse wave signal from an object;
- a force sensor configured to measure a first force exerted between the object and the pulse wave sensor;
- and
- a processor configured to:
- convert the first force into a second force, based on structure information of the object;
- and
- estimate the bio-information, based on the pulse wave signal and the second force.
A method of estimating bio-information, the method comprising:
- measuring a pulse wave signal from an object;
- measuring a first force exerted between the object and a pulse wave sensor;
- converting the first force into a second force, based on structure information of the object;
- and
- estimating the bio-information based on the pulse wave signal and the second force.
An electronic device for estimating bio-information of a user, the electronic device comprising a processor configured to:
- obtain, from a pulse wave sensor of the electronic device, a pulse wave signal of the user;
- obtain a first force value corresponding to a force exerted between an object of the user and the pulse wave sensor of the electronic device;
- obtain sensor position information indicative of a position of the pulse wave sensor with respect to the object of the user;
- obtain blood vessel position information indicative of a position of a blood vessel of the object of the user;
- identify a second force value, based on the first force value, the sensor position information, and the blood vessel position information;
- and
- estimate the bio-information, based on the pulse wave signal and the second force value.
