Abstract: An apparatus for estimating bio-information, the apparatus including a pulse wave sensor and a processor. The pulse wave sensor includes a plurality of channels, each channel of the plurality of channels being configured to measure a first pulse wave signal of a first wavelength and a second pulse wave signal of a second wavelength that is different from the first wavelength. The processor is configured to: for each channel of the plurality of channels, generate a first oscillogram based on the first pulse wave signal, generate a second oscillogram based on the second pulse wave signal, and convert a phase delay between the first oscillogram and the second oscillogram into an area. The processor is further configured to determine a channel among the plurality of channels based on the area of each channel, and estimate bio-information based on the determined channel.

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.
