METHOD OF POWERING AN ELECTRICALLY-CONTROLLED DEVICE WITH VARIABLE OPTICAL AND/OR ENERGY PROPERTIES

摘要

The invention relates to a method of powering an electrically-controlled system with variable optical/energy reflection or transmission properties, consisting of at least one carrier substrate which is equipped with a stack of layers enabling the migration of active species and comprising at least two active layers which are separated by an electrolyte, said stack being disposed between two electrodes which are connected respectively to lower and upper current supplies. The invention is characterised in that it consists in applying a second energy potential (P2, P2') between the current supplies, which can be varied as a function of time, together with a first constant energy potential (P1, P1'), said first and second energy potentials being adapted to ensure switching between two different optical/energy reflection or transmission property states, E1 and E2.
