摘要：
A method and system for extracting cardiac cycle parameters from a respiration signal is disclosed. The technique comprises an array of piezoelectric sensors planted on the chest. The chest membrane exhibits the characteristics of bulky attenuator with certain time delay. Contractions and expansions of the heart and lungs muscles model a mechanical load and produce a relative induced strain on the piezoelectric sheet which in turn causes the piezoelectric material to generate a corresponding conformal voltage signal that is mapped with the heart actions. The resultant voltage signal is therefore used to extract and model the corresponding heart parameters utilizing piezoelectric as well as signal processing theories. a direct relationship is established between the output voltage produced by the piezoelectric transducer under hold breathing and the respiration signal collected by the same transducer with respiration.
