When the studies in the literature on breast tumor diagnosis are examined, there are many studies because breast tissues have different characteristics. However, there is no study on the diagnosis of the tumor by constant frequency vibration stimulation and the response of healthy and tumorous breast tissues to this stimulation. This study, fixed frequency vibration was applied to the points determined on breast tissues and it was aimed to design a system that can measure vibration signals at certain distances from these points. The first part of the system consists of a motor and a driver that provides vibration. The other part includes accelerometer sensors that measure vibrations at certain points in the breast tissues. The hardware is controlled by a microcontroller-based module. With the help of this designed device, the power spectra of the vibration signals obtained by measurements on breast phantom models were analyzed. In response to 160 Hz vibration excitation, the dominant frequencies of the signals measured at a certain distance with the accelerometer sensor were found to be in the range of 120-140 Hz. These results show the damping effect of breast tissue and that the damping effect may differ between tumor and healthy tissues.
