Abstract

This letter reports a new technique that enables simultaneous detection of concentrations of the organic and inorganic substances in a hybrid fluidic solution. The technique is based on a coplanar microwave distributed MEMS transmission line. Measurement results show that a hybrid aqueous solution with a mixture of 0 M -- 0.2 M NaCl and 0 mg/ml -- 350 mg/ml glucose can be easily detected simultaneously from measured one-port scattering parameter (S11).
