Claim 4:
5. The method according to claim 4, wherein:
the pyroelectric material and/or the piezoelectric material and/or the ferroelectric material and/or the dielectric material comprises lead,
the one of the first separation layer and the second separation layer comprises SiO2, and
the method further comprises a step of reducing the initial adherence force of the interface between the first separation layer and the second separation layer comprising implementing at least one thermal treatment forming, at the interface between the first separation layer and the second separation layer, an alloy of lead and SiO2 in a liquid phase, then a cooling forming cavities at the interface between the first separation layer and the second separation layer.
