Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Quartz Crystal Microbalance (QCM) is widely used in many fields such as environmental monitoring, biomedical engineering, etc. The methods now used to measure resonant frequency of a QCM have some limitation on accuracy. So a new method of a signal processing system was proposed here for detecting QCM resonant frequencies, based on a novel approach of multi-sinusoidal signals. The QCM resonant frequency at a certain amplitude was obtained at its minimum impedance. Further research was given on the relationship between input voltage and resonant frequency. It reveals Multisim simulation processing can much effectively determine QCM resonant frequency by an impedance-frequency profile. It has shown a new avenue of real-time monitoring QCM resonant frequency.
