Abstract:
System, devices and methods are presented that integrate stretchable or flexible circuitry, including arrays of active devices for enhanced sensing, diagnostic, and therapeutic capabilities. The invention enables conformal sensing contact with tissues of interest, such as the inner wall of a lumen, a nerve bundle, or the surface of the heart. Such direct, conformal contact increases accuracy of measurement and delivery of therapy.
Abstract:
In embodiments, the present invention may attach at least two isolated electronic components to an elastomeric substrate, and arrange an electrical interconnection between the components in a boustrophedonic pattern interconnecting the two isolated electronic components with the electrical interconnection. The elastomeric substrate may then be stretched such that the components separate relative to one another, where the electrical interconnection maintains substantially identical electrical performance characteristics during stretching, and where the stretching may extend the separation distance between the electrical components to many times that of the unstretched distance.

Abstract:
A wearable device includes a flexible printed circuit board and one or more conductive stiffeners. The conductive stiffeners include a conductive surface that can be electrically or thermally connected to contact pads on the flexible printed circuit board. The wearable device can further include an adhesive layer or an encapsulation layer. The adhesive layer and the encapsulation layer can include conductive portions surrounded by non-conductive portions. The conductive portions can be aligned with the conductive stiffeners and together transmit electrical and/or thermal energy to the contact pads of the flexible printed circuit board.

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.
