%X Based on the transmission line model of piezoelectric sensor, acoustic impedance theory has been advanced to explain the response mechanism of piezoelectric sensor. By this theory some basic response equations for various loading on piezoelectric sensor were produced, specially for the cells adhesion. In addition the experiments were done to testify the theoretical model on sensor response to cell adhesive behaviors. The results showed there was a linear relationship between the frequency shift, Δf (Hz), and the concentration of cells, C (ml-1), in which the coefficient was 0.98 and the equation was Δf=-246C-20.1 (P<0.001).
