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

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

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 ...

Dynamics of capillary self-alignment for mesoscopic foil devices

Jürgen Brugger, Massimo Mastrangeli

We report experimental evidence for three sequential, distinct dynamic regimes in the capillary self-alignment of centimeter-sized foil dies released at large uniaxial offsets from equilibrium. We show that the initial transient wetting regime, along with ...

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

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

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 ...
