  The need for rapid fabrication of microfluidic devices has become
increasingly critical as microfluidics become part of biomedical sensors. Using
Warp and Weft Wiring (WWW) of copper wires, this paper presents a novel
low-cost method for rapid, self-aligned, bonding-free, and modifiable
fabrication of multi-electrodes microfluidic sensors. All the proposed features
are promising and highly recommended for the development of Point-of-Care Tests
(POCTs), while most of the conventional methods have low chances of coming out
of the research labs and play no role in POCTs development. To have an
experimental proof of concept, the proposed chip was fabricated and then tested
with two sets of experiments that showed the potential applications of water
quality management, hygiene, biomedical impedance measurement, cell analysis,
flow cytometry, etc.
