Abstract

Accurate fluid viscosity measurements are used to determine important fluid properties, necessary for a wide range of industries including food production, petroleum shelling and fracking, and pharmaceuticals, especially when testing minute volumes of fluid. Conventional methods of calculating the viscosity of a micro-volume fluid are expensive, require trained specialists to operate, and can require large bulky systems or additives to the fluid. We have developed a compact, inexpensive, easy-to-use, automated smartphone-based platform for measuring the viscosity of micro-volume fluids used in conjunction with an Arduino-controlled sensor-bed for holding the fluid sample. After applying a micro-volume fluid to the sensor-bed surface, a custom designed smartphone application is used to capture videos of the fluid’s response to an applied stimulus. Sensor data from the sensor-bed is simultaneously captured, via Bluetooth with each video, or can be added manually after capturing each video. These videos are then processed on a remote server to quantify the fluid’s response and the results returned to the originating smartphone. Results are shown to the user in the form of a calibration curve for determining the fluid’s viscosity. Previously processed fluids can be downloaded from the remote server and reviewed on the smartphone. Using this platform, we successfully demonstrated our system’s ability to measure the viscosity of unknown fluids after calibrating the system with fluids of known viscosity. This rapid, cost-effective, and portable platform can be used for measuring the viscosity of minute amounts of Newtonian or non-Newtonian fluids, especially useful for assessing medical conditions from blood viscosity.
