High frequency microrheological measurements of PDMS fluids using saw microfluidic system

In this paper authors report a method to determine the complex shear modulus of fluids using a Love wave acoustic sensor in oscillator mode. A combined measurement of frequency shift and insertion losses associated with the perturbation theory gives access to the storage modulus G′G′ and the loss modulus G″G″ of poly(dimethylsiloxane)s.
