ABSTRACT:
The subject of the invention is an electrically controllable device comprising at least one substrate provided with a functional stack of layers comprising at least two active layers separated by an electrolyte. The stack is placed between a lower electrode and an upper electrode. The device comprises n regions which are independently electrically controllable, using the lower electrode having a pattern A in one or two dimensions, the stack of layers, at least one of the active layers and the electrolyte of which having a pattern B in two dimensions, the upper electrode having a pattern C in two dimensions, so that the superposition of the patterns A, B and C, defines said n regions, with a physical discontinuity between two adjacent regions at least both at the level of the upper electrode and at the level of one of the active layers and of the electrolyte.
