METHOD AND SYSTEM FOR ASSEMBLING A MICROFLUIDIC SENSOR

摘要

A microfluidic sensor, such as an electrochemical blood test strip, with more accurate measurement comprises a plurality of channels through which a fluid to be tested flows via a capillary action. One or more electrodes are located under the channels. As the fluid flows over the electrodes in the channels, the impedance between the electrodes 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.

1. A double-sided microfluidic sensor, comprising:
A first cover layer; a second cover layer; and an electrode layer comprising a substrate having a first surface and a second surface, at least one electrode deposited on the first surface, and at least one electrode deposited on the second surface, wherein a first channel is formed between the first cover and the first surface of the electrode layer, a second channel is formed between the second cover and the second surface of the electrode layer, and the first channel and the second channel are configured to receive a fluid.
