Temperature measurement of electrical conductivity s were carried out from 395 to 543 K. The obtained dependence indicates an increase in s. The temperature dependence of the electrical conductivity allowed to observe the release of the free water, bound water and structural water. Studies on electric conductivity of collagen indicate the occurrence of percolation threshold, which comprises free release of water and change its properties from semiconducting to dielectric one.
