Abstract
This paper presents the development of a prototype circuit that measures the damping coefficient of a fluid-solid interface. By means of the under damped motion of a mass, it is possible to measure the damped angular frequency of the system, which is directly related to the damping ratio, caused by the fluid viscosity. A wireless sensing method is proposed, using an accelerometer, a microcontroller unit and two radio modules. Such an approach can yield an implementation that is flexible and adaptive to industrial and scientific applications.
