Abstract: The present inventive concept relates to a foldable layered connection comprising: a substrate having a first major surface and an opposing second major surface; a node of connector material arranged to contact the substrate via the first major surface; a released extension comprising a core of connector material arranged to be in communicative contact with the node of connector material, and flexible material arranged to at least partially enclose the core; wherein the released extension is configured to be hingedly connected to the node and to fold towards the second major surface, and wherein a portion of the core of connector material is exposed, forming a contact of connector material, wherein the contact is electrically isolated from the second major surface and arranged such that it is facing away from the second major surface when the released extension is folded towards the second major surface.

Abstract: Aspects of the present disclosure relate to a capillary fluidic device comprising at least two inlets, a microfluidic channel and an outlet. The device allows for the autonomous and programmable sequential flow of the same or different fluids using capillary fluidics for autonomous pumping of liquids to other downstream fluidic structures. External pumping and valving systems are not required, thus reducing complexity and increasing portability of stand-alone microfluidic systems. Aspects of the present disclosure can be applied to other fluidic structures for performing analytical biological assays. The integration has at least one reaction chamber and at least one capillary pump. The device is integrated with at least one sensor for detection and quantification of the biological assay signals.
