Method for manufacturing an electromechanical structure, comprising: producing (106) conductors and/or graphics on a substantially flat film, attaching (108) electronic elements on the said film in relation to the desired three-dimensional shape of the film, forming (110) the said film housing the electronic elements into a substantially three-dimensional shape, using (112) the substantially three-dimensional film as an insert in an injection molding process by molding substantially on said film, wherein a preferred layer of material is attached on the surface of the film, creating an electromechanical structure. A corresponding arrangement (500) for carrying out said method is also presented.
