Abstract
A method and apparatus for measuring blood pressure are provided. According to one or more exemplary embodiments, the apparatus for measuring blood pressure obtains a blood pressure value by applying a plurality of particular points, sampled at regular intervals from a pulse wave signal detected in an ear area of an object, to a pre-stored blood pressure estimation algorithm.
Claims20
An apparatus for measuring blood pressure, the apparatus comprising:
- an earphone device comprising:
- a light emitter configured to emit a light to an ear area of an object, and
- a light receiver configured to receive at least one of a light transmitted from the ear area, a light that is radiated from the light emitter and reflected by the ear area, and a light diffused from the ear area, and perform photodetection of the at least one light to measure a pulse wave signal;
- and
- a signal processor configured to obtain a plurality of particular points, which are sampled at regular intervals from a waveform of the pulse wave signal, and apply the plurality of particular points to a blood pressure estimation algorithm to obtain a blood pressure value.
