Organic-inorganic-hybrid-polymer microlens arrays with tailored optical characteristics and multi-focal properties

Jürgen Brugger, Victor Javier Cadarso Busto, Loïc Jacot-Descombes

Plano-convex microlens arrays of organic-inorganic polymers with tailored optical properties are presented. The fine-tuning of each microlens within an array is achieved by confining inkjet printed drops of the polymeric ink onto pre-patterned substrates. ...

Liquid-Filled Sealed Mems Capsules Fabricated By Fluidic Self-Assembly

Jürgen Brugger, Massimo Mastrangeli, Rosario Maurizio Gullo, Loïc Jacot-Descombes

We present a new method to encapsulate functional liquids into sealed MEMS capsules by fluidic self-assembly. Self-assembly of 200 mu m SU-8 cargos and picoliter liquid co-encapsulation are driven by the interplay of global fluidic drag and short-range cap ...

Inkjet printed superparamagnetic polymer composite hemispheres with programmed magnetic anisotropy

Jürgen Brugger, Massimo Mastrangeli, Victor Javier Cadarso Busto, Christofer Hierold, Loïc Jacot-Descombes, Rosario Maurizio Gullo, Berna Ayse Özkale Edelmann

We present the fabrication and characterization of large arrays of inkjet-printed superparamagnetic polymer composite (SPMPC) hemispherical microstructures. SPMPCs are appealing for applications in microsystems and nanorobotics due to the added functionali ...

In-liquid MEMS assembly by optical trapping

Jürgen Brugger, Rosario Maurizio Gullo, Loïc Jacot-Descombes

This paper presents a novel in-liquid method to manipulate and micro-assemble MEMS in 3D by means of holographic optical trapping and hydrophobic interaction. Up to eight traps can be simultaneously generated with a trapping stiffness of 5 pN/mu m each. SU ...

Inkjet-printed SU-8 Hemispherical Microcapsules and Silicon chip Embedding

Jürgen Brugger, Massimo Mastrangeli, Victor Javier Cadarso Busto, Rosario Maurizio Gullo, Loïc Jacot-Descombes

Planar lithography techniques are not effective for precise fabrication of microdevices with hemispherical shapes. Drop-on-demand (DOD) inkjet printing (IJP) of photo-curable ink is a more appropriate fabrication approach as it takes advantage of the surfa ...

Fluid-mediated parallel self-assembly of polymeric micro-capsules for liquid encapsulation and release

Jürgen Brugger, Alcherio Martinoli, Luis Guillermo Villanueva Torrijo, Massimo Mastrangeli, Cristina Martin Olmos, Victor Javier Cadarso Busto, Loïc Jacot-Descombes, Grégory Mermoud, Rosario Maurizio Gullo

Fluid-mediated self-assembly is one of the most promising routes for assembling and packaging smart microsystems in a scalable and cost-efficient way. In this work the pairwise fluidic self-assembly of 100 μm-sized SU-8 cylinders is studied with respect to ...

Acousto-fluidic system assisting in-liquid self-assembly of microcomponents

Jürgen Brugger, Alcherio Martinoli, Massimo Mastrangeli, Rosario Maurizio Gullo, Loïc Jacot-Descombes, Grégory Mermoud, Helmut Knapp

In this paper, we present the theoretical background, design, fabrication and characterization of a micromachined chamber assisting the fluidic self-assembly of micro-electro-mechanical systems in a bulk liquid. Exploiting bubble-induced acoustic microstre ...

Heterogeneous material micro-transfer by ink-jet print assisted mould filling

Jürgen Brugger, Grégoire Maxime Smolik, Victor Javier Cadarso Busto, Loïc Jacot-Descombes, Vaida Auzelyte

A novel combination of ink-jet printing (IJP) and micro-transfer moulding (μ-TM) for high-resolution, heterogeneous material microstructuring is demonstrated. First, IJP is used to accurately fill the micro-cavities in an elastomeric mould, thus avoiding t ...

Fabrication of epoxy spherical microstructures by controlled drop-on-demand inkjet printing

Jürgen Brugger, Victor Javier Cadarso Busto, Rosario Maurizio Gullo, Loïc Jacot-Descombes

Well-controlled spherical microstructures open new possibilities for several MEMS devices, such as hemispherical microfluidic channels or micro-optical elements. However, machining of micro-spherical shapes has proven to be difficult with conventional plan ...
