Heart motion and blood ejection during the cardiac
cycle originates a set of body vibrations that are sensed through
the usage of different sensing systems that provide the
information on cardiac mechanics and cardiac output.
Ballistocardiogram (BCG) and seismocardiogram (SCG) are the
recording of body vibration induced by heart bit. The sensing of
the BCG requires mechanical contact between the user body
parts equipment and furniture embedded BCG sensing to
provide data for that can be used to validate the BCG models.
The heart activity generates a set of forces and reverberations
that may be modeled in two directions, anteroposterior and
dorsoventral. As the ballistocardiogram sensing is usually done at
the person’s back or at the posterior pelvic region the cardiac
forces models are associated with these two directions.
Additionally a set of results including the designed models
simulations and the BCG validation signals obtained from BCG
sensing systems prototypes are included in the paper.
