Web• Contact Impedanceof the skin for humans, and hoofs or paws for animals tends to be at least 30 times greater than the internal tissue impedance, therefore the contact impedance and the environment (wet, salty sweat, or dry) becomes the dominant variable • Human Body Impedance- For dry conditions, 1000 ohms is frequently cited WebVarious models of human body impedance have been developed and described in the literature [15], [17]–[19]. The model of human body impedance given in the IEC 479-1 report is shown in Fig. 1(a). It consists of a series connection of skin impedances (Zp1, Zp2) and of internal impedance Zi. Skin impedance is the function of touch

The electrical properties of tissues have been described since 1872. These properties were further described for a wider range of frequencies on a larger range of tissues, including those that were damaged or undergoing change after death. In 1962, Thomasset conducted the original studies using electrical impedance measurements as an index of total body water (TBW), using two subcutaneously inserted needles.
