Patent ID: 7196385

Claim:
An electromechanical microstructure comprising: a first mechanical part formed in a first electrically conductive material, and which comprises (1) a zone deformable in an elastic manner having a thickness value and an exposed surface and (2) a first organic film having a thickness, present on a whole of the exposed surface of the deformable zone, wherein the first organic film is bonded in a covalent manner to the exposed surface of the deformable zone and formed from an electro-initiated reaction; an annular zone at a surface of the first mechanical part, surrounding the exposed surface, having itself a surface and formed in a second electrically conductive material, different in a sense of the electro-initiated reaction from the first electrically conductive material of the first mechanical part; and a second organic film present on the surface of the annular zone, the second organic film formed in a material that may be deposited from an electro-initiated chemical reaction.
