  • Method for producing a multilayer piezoelectric microcomponent using sacrificial thick film technology
    Patent number: 8287943
    Abstract: The invention relates to the preparation of multilayer microcomponents which comprise one or more films, each consisting of a material M selected from metals, metal alloys, glasses, ceramics and glass-ceramics. The method consists in depositing on a substrate one or more films of an ink P, and one or more films of an ink M, each film being deposited in a predefined pattern selected according to the structure of the microcomponent, each film of ink P and each film of ink M being at least partially consolidated before deposition of the next film; effecting a total consolidation of the films of ink M partially consolidated after their deposition, to convert them to films of material M; totally or partially removing the material of each of the films of ink P. An ink P consists of a thermoset resin containing a mineral filler or a mixture comprising a mineral filler and an organic binder. An ink M consists of a mineral material precursor of the material M and an organic binder.
