Abstract: The present disclosure provides a wavy physiological signal collecting device and a physiological signal collecting mattress. The device includes a wavy flexible body including a flexible body panel and a plurality of protruding flexible bodies each of which is arranged on the flexible body panel for converting a human body pressure applied thereto to a tensile force; a tensile force sensor arranged in the flexible body panel for generating an electrical signal according to the tensile force; and a signal processing unit configured for processing the electrical signal to obtain a human body physiological signal. The wavy flexible body converts the human body pressure to an electrical signal and processes the electrical signal, thereby obtaining the human body physiological signal in daily life without directly contacting human skin, allowing the physiological signal to be obtained more conveniently.

Abstract: The present disclosure provides a method and a system for obtaining a cycle of a physiological signal. The method includes: receiving a physiological signal value and a register value, comparing the physiological signal value with the register value, and reserving one of the physiological signal value and the register value; determining the physiological signal value with a time duration thereof reaching a given set time to be an extreme value; and restarting the procedure and determining a next extreme value; and obtaining a cycle of the physiological signal by calculating a time difference between the extreme value and the next extreme value. In the present disclosure, the cycle of the physiological signal can be obtained by the extreme value recognition algorithm, which is simple, fast, of high efficiency, and of high reliability.
