Abstract: A physiology signal sensing device includes an elastic pad and a strain sensor element. The elastic pad is used for contact with a human body, and corresponds a blood vessel of the human body. The strain sensor element is disposed in the elastic pad and includes a conductive element. The conductive element deforms according to the vibration of the blood vessel, and the resistance value of the conductive element varies according to the strain of the conductive element.

Abstract: The present invention provides a system and method for blood pressure measurement, a computer program product using the method, and a computer-readable recording medium thereof. The present invention uses a sensor to measure an electrophysiological signal and establishes a personalized cardiovascular model through a numerical method, and re-establishes the personalized cardiovascular model through an optimization algorithm. Thus, a human physiological parameter generated from the re-established personal cardiovascular model matches the electrophysiological signal. Therefore, the present invention can provide accurate measurement results with the advantage of a small size, and can be applied to telemedicine field.
