Design and modeling problems of resonance piezoelectric tactile arrays

The resonance piezoelectric tactile array sensors offer the means of measuring not only the presence of applied mechanical stress but also the stress intensity. The problem in such kind of resonance sensors is the real time mode of operation. The sensibility array field is scanned in consecutive way thus hampering the sensor from coping with dynamically changing mechanical stresses. It is useful to define a model for describing the sensor behavior which takes into account the array structure and uses it to diminish its disadvantages in regards to real time mode operations. For this purpose a one-dimensional mathematical utilizing transformed form of Sauerbrey equation is under investigation for applicability for the resonance piezoelectric array sensors. The aim for researched model is the proximity with the real processes to be achieved as well as quantitative solutions for the resonance sensor system to be in reach.
