Abstract

Systems, methods and apparatuses for monitoring cardiac activity of an individual using a conformal cardiac sensor device are presented herein. A conformal cardiac sensor device for analyzing cardiac activity includes a flexible substrate for coupling to the user, and a heart sensor component embedded on/in the substrate. The heart sensor component contacts a portion of the users skin and measures electrical variable(s) indicative of cardiac activity. A biometric sensor component is embedded on/in the flexible substrate and measures physiological variable(s) indicative of cardiac activity of the user. A microprocessor, which is embedded on/in the flexible substrate, is communicatively coupled to the heart sensor component and biometric sensor component and operable to execute microprocessor executable instructions for controlling the measurements of electrical data and physiological data. A wireless communication component is embedded on/in the flexible substrate and is operable to transmit data indicative of the measurements obtained by the sensor components.
