Abstract
Techniques regarding one or more microfluidic chips with integrated electronic sensors are provided. For example, one or more embodiments described herein can regard an apparatus that can comprise a conductive plug of a reference electrode structure, the conductive plug extending from within a microfluidic channel to within a reference fluid holding chamber that is in fluid isolation from the microfluidic channel.
Claims20
An apparatus, comprising:
- a conductive plug of a reference electrode structure, the conductive plug extending from within a microfluidic channel to within a reference fluid holding chamber that is in fluid isolation from the microfluidic channel.
A method, comprising:
- depositing a conductive plug onto a substrate surface;
- and
- forming, via an additive process, a microfluidic channel and a reference fluid holding chamber on the substrate surface such that a wall between the microfluidic channel and the reference fluid holding chamber extends across the conductive plug.
A method comprising:
- fabricating a microfluidic channel and a reference fluid holding chamber from a polymer material;
- and
- inserting a metal wire through a wall that isolates the microfluidic channel from the reference fluid holding chamber such that a first portion of the metal wire is positioned within the microfluidic channel and a second portion of the metal wire is positioned within the reference fluid holding chamber.
