Biomechanical Signals
Mechanical functions of biological systems, which include motion, displacement, tension, force, pressure, and flow, also produce measurable biological signals. Blood pressure, for example, is a measurement of the force that blood exerts against the walls of blood vessels. Changes in blood pressure can be recorded as a waveform. The upstrokes in the waveform represent the contraction of the ventricles of the heart as blood is ejected from the heart into the body and blood pressure increases to the systolic pressure, the maximum blood pressure. The downward portion of the waveform depicts ventricular relaxation as the blood pressure drops to the minimum value, better known as the diastolic pressure.
