Method and apparatus for estimating blood pressure

A computer program product comprising a computer readable computer program code for executing a method of estimating blood pressure and instructions for causing a computer to implement the method, the method comprising:

• sensing a sphygmus wave at a body part of a user to which vibration is applied to generate a sensed sphygmus wave;
• filtering the sensed sphygmus wave to generate a filtered sphygmus wave;
• and
• estimating blood pressure of the user based on time differences between peaks of the sensed sphygmus wave peaks of the filtered sphygmus wave.

An apparatus for estimating blood pressure, the apparatus comprising:

• a sensing unit which senses a sphygmus wave at a body part of a user to which vibration is applied to generate a sensed sphygmus wave;
• a filtering unit which filters the sensed sphygmus wave to generate a filtered sphygmus wave;
• a blood pressure estimation unit which estimates blood pressure of the user based on time differences between peaks of the sensed sphygmus wave and peaks of the filtered sphygmus wave;
• and
• a user interface unit which outputs estimated blood pressures.
