Volume refractometry of liquids using stable optofluidic Fabry-Perot resonator with curved surfaces

This work reports a simple, miniaturized optical sensing module for liquid refractometry. It is based on a stable Fabry-Perot resonator consisting of two silicon cylindrical mirrors with a cylindrical lens in the core. The lens is formed by a capillary tub ...

La coupe du roi and other methods to halve objects

Dieter Schwarzenbach

The symmetry theory of halving objects into two identical fragments is developed and illustrated by examples. La coupe du roi is a fascinating way to slice an apple into chiral fragments with the same handedness. It may be applied to any object with point ...

Strength of glass determined by the relation of the critical flaw to the fracture mirror

Jean-Paul Lebet, Maria Lindqvist

Tensile strength of structural glass elements is highly influenced by flaws. For this paper, the study concentrates on the fracture origin i.e. the critical flaw, situated at the edge of a glass element. In the current study the influence of two different ...

Parity-time symmetric metamaterials and metasurfaces for loss-immune and broadband acoustic wave manipulation

Romain Christophe Rémy Fleury

We explore the largely uncharted scattering properties of acoustic systems that are engineered to be invariant under a special kind of space-time symmetry, consisting in taking their mirror image and running time backwards. Known as Parity-Time symmetry, t ...

A two-arm coordination model for phantom limb pain rehabilitation

Ronan Boulic, Eray Molla

Following limb loss, patients usually continue having sensations on their missing limbs as if they were still present. Signicant amount of such sensations are painful and referred as Phantom Limb Pain (PLP). Previous research has shown that providing the p ...

Design and fabrication of a novel centimeter scale three dimensional silicon tip, tilt and piston mirror mechanism

François Barrot, Dara Zaman Bayat, Johannes Richard Cornelis Geerit Kruis, Rémy Fournier

A novel centimetre scale tip tilt piston mirror mechanism has been designed in silicon. The mirror consists of three identical mechanism parts and one mirror part. The fabrication of the parts was done with photolithography and Deep Reactive Ion Etching an ...

Study of polyvinylidene fluoride (PVDF) based bimorph actuators for laser scanning actuation at kHz frequency range

Hannes Bleuler, Ricardo Pérez Suárez

This work focuses on some promising applications of polyvinylidene fluoride (PVDF) based bimorph actuators in microengineering. The actuator of several centimeters in length and 100 mu m in thickness takes advantage of the structural and electromechanical ...

Embedded microstructures for daylighting and seasonal thermal control

Jean-Louis Scartezzini, Yves Leterrier, Andreas Schueler, André Gabriel Kostro, Mario Geiger, Nicolas Jolissaint

A novel concept for an advanced fenestration system was studied and samples were produced to demonstrate the feasibility. The resulting novel glazing will combine the functions of daylighting, glare protection, and seasonal thermal control. Coated microstr ...

Enhanced Wavefield Separation of OBS Data

Loïc Arnaud Baboulaz

In ocean-bottom seismic (OBS) data processing, wavefield separation results are sometimes affected by high levels of noise on the vertical component Z, while the pressure component P is in general of good quality. Nonetheless, Z is needed to achieve comple ...

Fabrication and characterization of 3D integrated 2 DOF Micromirror Arrays for excessive thermal loads

Nico de Rooij, Caglar Ataman, Wilfried Noell, Fabio Jutzi, Sébastien Lani, Dara Zaman Bayat

This paper reports a high fill-factor (>90%), 2-dimensional analog micromirror array designed specifically for very high, optically induced thermal load applications. Each pixel can attain a mechanical DC rotation angle of ±4 degrees around any arbitrary a ...
