“…The important simulation parameters for the microfluidic viscometer include the range of viscosities and flow rates as well as the micropillar and channel dimensions. Following the design parameters utilized in our previous experimental work [21,22], we examined a viscosity range of µ = 5-100 cP, and a flow rate between Q = 15-105 mL/h. For the micropillar and channel dimensions, we set the diameter of the micropillars at D = 300 µm, and varied the pillar aspect ratio ( AR) between 3 and 5, corresponding to a pillar height between H = 900 and 1500 µm.…”

“…We have recently developed a novel method for measuring the viscosity of Newtonian and non-Newtonian fluids [21,22]. This method involves fluid-structure interactions and measures the deflection of elastic polydimethylsiloxane (PDMS) micropillars in response to fluid flow to determine the viscosity.…”

“…We employed multiphysics simulations to examine how changes in these parameters impact the sensitivity of the viscometer. These simulations are based on multiphysics models that we developed and experimentally validated in our previous studies [21,22] (also see Section S2 in Supplementary Materials). Our results will help advance the application of this microfluidic viscometer to a broader range of fluids and facilitate custom viscometer design towards specific applications.…”

Fluid-structure interactions (FSI) are used in a variety of sensors based on micro- and nanotechnology to detect and measure changes in pressure, flow, and viscosity of fluids. These sensors typically consist of a flexible structure that deforms in response to the fluid flow and generates an electrical, optical, or mechanical signal that can be measured. FSI-based sensors have recently been utilized in applications such as biomedical devices, environmental monitoring, and aerospace engineering, where the accurate measurement of fluid properties is critical to ensure performance and safety. In this work, multiphysics models are employed to identify and study parameters that affect the performance of an FSI-based microfluidic viscometer that measures the viscosity of Newtonian and non-Newtonian fluids using the deflection of flexible micropillars. Specifically, we studied the impact of geometric parameters such as pillar diameter and height, aspect ratio of the pillars, pillar spacing, and the distance between the pillars and the channel walls. Our study provides design guidelines to adjust the sensitivity of the viscometer toward specific applications. Overall, this highly sensitive microfluidic sensor can be integrated into complex systems and provide real-time monitoring of fluid viscosity.
