Abstract
An apparatus for estimating bio-information includes a sensor part configured to measure a pulse wave signal and a contact force of an object, while the object is in contact with the sensor part. The apparatus further includes a processor configured to extract a first feature from the measured pulse wave signal and the measured contact force, select one estimation model from a plurality of estimation models, based on a second feature of a user corresponding to the object, and estimate the bio-information, by inputting the extracted first features in the selected estimation model.
