1. A method for estimating blood pressure, 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 and peaks of the filtered sphygmus wave.
