Plastic functional element

摘要

A plastic functional element comprising a lower electrode and a transparent upper electrode provided perpendicular to the contact surface between a first oxidation reduction material membrane and a second oxidation reduction material membrane, the oxidation reduction potentials of which being different each other, wherein, based on the difference in oxidation reduction potentials between the oxidation reduction material membranes, by irradiating light to the contact surface or applying a voltage between the electrodes, the condition of electron in the oxidation reduction material is controlled, so as to store information of incident light or applied voltage, and an operational function responding to an input voltage is given, thereby the minimization in size is possible to realize a high density and high speed operation.
