Abstract: The packaging device of a microbattery arranged on a flexible support comprises at least one thin layer forming a protective barrier deposited on the whole of the microbattery, and a flexible compensation cover above the barrier. The cover is made from a material, for example polymer, with a thickness tcomp and a Young's modulus Ecomp chosen such that the neutral plane of the assembly is situated at the level of the microbattery. The thickness of the cover is calculated, with an accuracy of ±30%, by the equation t comp = t sub ? in which tsub is the thickness of the support and ? the ratio of the Young's moduli of the cover and of the support.
