Nanoindentation cracking in gallium arsenide: Part II. TEM investigation

Johann Michler, Jacques Giovanola, Jean-Daniel Ganière, Jean-Marc Breguet, Cédric Pouvreau

The nanoindentation fracture behavior of gallium arsenide (GaAs) is examined from two perspectives in two parent papers. In the first paper (part I), we address the morphology of the crack field induced by different types of indenters by means of in situ n ...

Nanoindentation cracking in gallium arsenide: Part I. In situ SEM nanoindentation

Johann Michler, Jacques Giovanola, Jean-Marc Breguet, Cédric Pouvreau

The nanoindentation fracture behavior of gallium arsenide (GaAs) is examined from two perspectives in two parent papers. The first paper (part I) focuses on in situ nanoindentation within a scanning electron microscope (SEM) and on fractographic observatio ...

Tunable Extended-cavity Diode Laser Based on a Novel Flexure-mechanism

Simon Nessim Henein, Jean-Marc Breguet

This article presents the design, implementation and characterization of a Littman-Metcalf extended-cavity diode laser. The extended cavity is closed by a roof (retro-reflecting) prism. The wavelength tuning is based on a two degrees-of-freedom monolithic ...

Friction based locomotion module for mobile MEMS robots

Reymond Clavel, Jean-Marc Breguet, Amar Rida, Walter Driesen

The “Modulated Friction Inertial Drive (MFID) principle” is presented as a locomotion solution for mmsize micro robots dealing with both size constraints and limitations in terms of power consumption. Based on one of the configurations of this locomotion p ...

Unified mechanical approach to piezoelectric bender modeling

Jean-Marc Breguet, Robert Dunsch

Anewanalytical modeling approach for piezoelectric bending elements is described. The approach is based on the beam theory under quasi-static equilibrium condition. It uses the theory of superposition of piezoelectric action in the bender and external mome ...

Applications of piezo-actuated micro-robots in micro-biology and material science

Jean-Marc Breguet, Walter Driesen, Tomas Cimprich

This paper presents a few examples of manipulators and micro-robots based on piezo-actuators developed during the last 4 years in the Laboratoire de Systèmes Robotiques (LSRO) at EPFL. Three working principles will be described (bender, inch-worm, inertial ...
