GOMEZ-AGUILAR, F. et al. Frequency response of an electric equivalent circuit for a skin type system. Rev. mex. ing. bioméd [online]. 2011, vol.32, n.2, pp.93-99. ISSN 2395-9126.

In the present work we consider a theoretical representation of an electrical circuit equivalent to a multilayer biological system. The proposed system is of the skin type, containing epidermis, dermis and the subcutaneous tissue. Electrical circuit theory is used, and the behavior of the system is shown in the form of Nyquist and Bode plots. The proposed theoretical approach is a general treatment to describe the bioelectrical transport in a three-layered system, especially in the electrical impedance spectroscopy studies.
