Investigation of Bacterial Cellulose-based Fractional Order Element behaviour

In this paper, the study of a constant phase element is presented. The device is realized by Bacterial Cellulose imbibed with Ionic Liquids. In particular, the realized device is investigated in a wide interval of time, with constant nominal working conditions. The authors demonstrate the fractional nature of the device in a very large frequency range. An Equivalent Electric Circuit Model is provided, giving evidence of its fractional-order nature.
