The microwave-microfluidic flow sensor. (a) Schematic design of the flow sensor integrating the microfluidic chip with the microwave resonator. (b) The flow through the microchannel deforms the thin polymer layer detectable by the change of permittivity of the environment measured by the resonator placed underneath. (c) The fabricated microwave-microfluidic resonator. Scale bar: 5 mm.
