This review paper briefly mentions the theoretical background for impedance spectroscopy. Also, this paper describes impedance testing methods for thin films, ceramics, crystals, liquids, and living bodies. I have categorized examples of impedance measurements and analyses of thin films (SrBi$_2$Ta$_2$O$_9$, SBTO), crystals (KH$_2$PO$_4$, KDP), ceramics (Pb$_x$La$_{1-x}$Zr$_y$Ti$_{1-y}$O$_3$, PLZT), emulsions, and the living body and introduced the results of this study. In particular, impedance measurement of a living body has proposed a needle-shaped sample cell in which a sample cell can measure the tissue of a living body. This suggests that the change in blood glucose level and the permittivity is related to each other in a living body. Impedance spectroscopy is a long-standing experimental method, so wider applications and developments in the industrial and the academic fields are expected in the future.
