Experimental Characterization of Drobot: Towards Closed-Loop Control

Massimo Mastrangeli, Pierre Lambert

This paper presents advances in the development of a microrobotic platform actuated by three liquid droplets in a gaseous environment (Drop-bot or Drobot). Drobot builds on the bubble robotics concept earlier introduced by Lenders [1]. A new platform desig ...

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 ...

Lateral capillary forces

Massimo Mastrangeli, Pierre Lambert

Lateral capillary forces ensuing from perturbed fluid menisci are pivotal to many important technologies, including capillary self-alignment and self-assembly of heterogeneous microsystems. This chapter presents a comprehensive study of the quasi-statics o ...

Vertical excitation of axisymmetric liquid bridges

Massimo Mastrangeli, Pierre Lambert

This study presents an analytical model of the dynamics of an axisymmetric liquid bridge confined between two circular pads and subjected to small vertical periodic perturbations. Such system finds important applications in microassembly and microjoint des ...

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 ...

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 ...

American Institute of Physics2013

This chapter reviews the capillary self-assembly (SA) of heterogeneous systems composed by milli- to micrometer-sized building blocks. The representative, though not exhaustive, examples of microsystems presented belong to four main classes: two-dimensiona ...

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 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 ...

The fabrication of precise hemispherical shape is challenging with standard planar lithography techniques. A suitable alternative is the fabrication by inkjet printing. This paper presents a method based on drop-on-demand inkjet printing on pre-patterned s ...
