Development of an Experimental Quartz Crystal Microbalance – MCQ as a tool for teaching modern physics

Gilson Tavares de Lima Poliana Guerino Marson Helcileia Dias Santos About the authors

In this article we describe the construction and operation of a low-cost experimental MCQ to demonstrate the use of quartz sensors for micro gravimetric analysis in liquid medium. For this, the Arduino micro® platform was used to control the interface with the computer, as well as a frequency meter for sensor excitation. A free graphic interface for computers was used to control the experiment and display the data obtained in real time. Applications of the experimental model and analysis of detection capabilities were also presented.
