Abstract (en)
[origin: EP0713773A2] The system to generate micro drops, especially for an ink-jet printer, has a housing (1) with a chamber (5) containing a number of piezo electric bending transducers. The chamber (5) has dividing walls (26) between them at least near the second end (16), opposite the first end fixed to the housing (1). The dividing walls (26) are processed to give electroplated deposits of metal, or through anisotropic etching of monocrystalline silicon, or through photographic structuring of photo varnishes or films. The upper transducer surface has a cladding, which is not electrically conductive, such as of organically modified ceramics, an epoxy resin, an acrylate polymer or of polyurethane.
