abstract |
In this paper, the design, fabrication and experimental analysis of a piezoelectrically
actuated micro squeeze flow rheometer is presented. Being only 30x30x0.5mm in size,
the micro rheometer is sensitive to very small volumes of the order of 1-10nL of liquid
and light enough to operate at frequencies in the kHz regime, an order of magnitude
higher than normally attainable with conventional cone and plate rheometry. Initial
experiments show that the response of the rheometer is dependent on the viscoelasticity
of the fluid being tested. The prototype was used to measure the moduli of poly(dimethylsiloxane)
(PDMS) of viscosity 10Pas, a non-volatile viscoelastic fluid, over the frequency range
of 10-1000Hz. Results show good agreement between with the moduli measured using conventional
rheometry up to 100Hz and with values extrapolated up to 1kHz. |
