A microfluidic sensor (10), such as an electrochemical blood test strip, with more accurate measurement comprises a plurality of channels (24) through which a fluid to be tested flows via a capillary action. One or more electrodes (30) are located under the channels (24). As the fluid flows over the electrodes (30) in the channels (24), the impedance between the electrodes (30) may be measured to determine fluid properties. In order to increase the accuracy of the measurements, the electrode deposition may be configured to be less than 10 μm in thickness via a printing process with high process consistency, thereby reducing the disruption of the electrode deposition on the fluid flow. |
