Mathematical and physical modelling of the dynamic electrical impedance of a tooth
Georgios Giannoukos, Mart Min · AIP conference proceedings · 2015
In this paper a detailed mathematical and physical model is presented in order to calculate the impedance of a tooth. The proposed model is based in an op-amp balanced Wien bridge oscillator and a voltage divider. From the amplitude of the signal and the phase shift we can calculate the resistance and the capacitance of a tooth.
