A fluidic device (10) is provided that includes a body (11) and a contiguous electrically conductive layer (100). The body (11) has interior and exterior surfaces. The interior surface defines at least a well (50) and a fluid-transporting feature (25), e.g., a microfeature in fluid-communication with the well (50). The well (50) has a sidewall (46S) and an exterior opening (46E) terminating at the exterior surface (44). The contiguous electrically conductive layer (100) is located on at least the sidewall (46S) of the well (50) and selected regions of the interior and exterior surfaces so as to form a contact pad region (102) on the exterior surface (44) in electrical communication with any fluid within the fluid-transporting feature (25). Also provided is a method for forming a fluidic device (10).
