Abstract
In various embodiments, a physiological or behavioral signal is derived from a vertical force resulting from the entire weight of a subject. A system for measuring physiological and behavioral signals in a human subject may include a measurement platform for bearing the subject, at least one force sensor for measuring vertical force imparted by an entire weight of the subject, and a signal processor for deriving at least one physiological or behavioral signal, such as a ballistocardiogram, from the measured force. The force sensor(s) may support the measurement platform and be disposed between the measurement platform and a support surface.
