N2 - This work presents a screen printed sensor that integrates the monitoring of flow velocity and thermal conductivity of a fluid in a microchannel. A modified anemometer principle is utilized to determine the flow velocity, which accounts for spurious heat transfer paths, e.g., in the substrate of channel walls. The sensor is fabricated by screen printing and tested using three different fluids at varying flow velocities. It is shown that the devised sensor setup is feasible for sensing both, flow velocity and thermal conductivity.
