Acta Medica Okayama 44 3 1995 Automatic sensing device of electrical characteristics of living trees 729 732 EN Yoshitake Yamamoto Hiroshi Harada Kiyotaka Yasuhara Takao Nakamura <p>The electrical impedance of a living tissue reflects its cell construction and physiological activity. For this purpose we developed an automatic sensing device of electrical tissue characteristics. The system is composed of a part measuring impedance at multifrequency points and a part analyzing parameters of dispersion of bioelectrical impedance, impedances are measured at eight frequency points of 1 kHz-500 kHz. The parameters for Cole-Cole arc's law are determined automatically by a personal computer program </p> No potential conflict of interest relevant to this article was reported.
