Biosignal measurement apparatus and method

A biosignal measurement apparatus, wherein the biosignal measurement apparatus comprises a data processing unit, and a first sensor, which is attachable to a surface of a body section at or adjacent to ribs and/or a neck and configured to convert movement pulses of the body section directly caused by muscular work of a heart at systolic and diastolic phases into pulses of an electric signal, the movement pulses of the body section directly caused by the muscular work of the heart being independent from a movement caused by changes of blood pressure in veins;

• and
• the data processing unit is configured to receive the electric signal from the first sensor, and form and output data about blood pressure on the basis of a characteristic feature of at least one of the movement pulses associated with the systolic phase and/or a characteristic feature of at least one of the movement pulses associated with the diastolic phase.
