A Comparative Study of Different Human Skin Impedance Models

This paper presents a comparative study of different human skin impedance models using meta-heuristic optimization Flower Pollination Algorithm (FPA). Four different models: Montague, Tregear, Lykken, and modified Montague skin models were used. There are two categories of electrical modelling; the RC-based model and the CPE-based model. The RC-based model focuses on skin stratification, while the CPE-based model focuses on the skin's biological properties. Six samples were taken as an experiment to acquire the skin impedance data to find the most accurate fitting model.
