An excerpt of signals acquired from subject #018. The six recorded signals represented from top to bottom are: ECG (blue); FCGPZT (red); FCGPVDF (orange); SCG (violet); Respiration (green); PCG (grey). (a) a 200-seconds segment including quiet breathing and apnea phases; the graph area with green background corresponds to the inspiratory apnea, while the graph area with red background corresponds to the expiratory apnea; (b) a 14-seconds segment including 20 heartbeats and 4 respiratory cycles during quiet breathing.
