Micro-Air-Bag Actuated Tunable Optofluidic Elements

Demetri Psaltis, Andreas Vasdekis, Wuzhou Song, Jae-Woo Choi

We introduce for the first time a tuning mechanism for optofluidic devices by embedding a Micro-Air-Bag (MAB) actuator inside a microfluidic chip. Multiple tunable optical elements controlled through the pressure of compressed air were demonstrated. (C)200 ...

SCALABLE CASCADED SNAP-IN ACTUATORS FOR LARGE-STROKE DISPLACEMENTS

Nico de Rooij, Wilfried Noell, Yves Pétremand, Nicolas Bernard Golay

This paper will focus on the design, and first measurements of a cascaded in-plane parallel plate snap-in actuator. The actuator is based on a rather simple microfabrication process and can achieve a total displacement of several tenths of microns. Compare ...

Modification of Conductivity and of Mechanical Properties of Electroactive Polymer (EAP) Thin Films by Titanium Ion Implantation

Herbert Shea, Samuel Rosset, Muhamed Niklaus

We present a study of the influence on Youngs modulus, stress and electrical conductivity of poly-dimethylsiloxane membranes implanted with titanium ions at energies from 5 to 35 keV, with doses up to 8x10^16 ions/cm2. The motivation for this study was to ...

Voltage control of the resonance frequency of dielectric electroactive polymer (DEAP) membranes

Herbert Shea, Samuel Rosset, Muhamed Niklaus

We report on the characterization, active tuning and modeling of the first mode resonance frequency of dielectric electroactive polymer (DEAP) membranes. Unlike other resonance frequency tuning techniques, the tuning procedure presented here requires no ex ...

A modular actuator system for miniature positioning systems

Thomas Maeder, Jean-Marc Breguet, Giancarlo Corradini, Arvid Bergander, Christophe Canales, Guillaume Boetsch

Monolithic actuators have turned out to be an efficient solution to several design and assembly problems associated with inertial drive positioning systems. In addition to their compact size with a possible thickness below 1.5 mm, the modular actuators pre ...

Mechanical characterization of a dielectric elastomer microactuator with ion-implanted electrodes

Herbert Shea, Samuel Rosset, Muhamed Niklaus

We report on the mechanical characterization and modeling of a non-prestretched dielectric elastomer diaphragm microactuator with ion-implanted electrodes under the influence of a distributed load (pressure). Thin polydimethysiloxane (PDMS) membranes (30 u ...

Micromirror array for multiobject spectroscopy in ground-based and space telescopes - art. no. 70182S

Nico de Rooij, Wilfried Noell

We are developing single-crystalline silicon micromirror arrays (MMA) fro future generation infrared multiobject spectroscopy (IR MOS). The micromirrors are 100 mu m x 200 mu m in size and can be tilted by electrostatic actuation yielding a tilt-angle of 2 ...

Ion-implanted compliant and patternable electrodes for miniaturized dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Muhamed Niklaus

This article presents metal ion implantation as an alternative technique to fabricate compliant electrodes for small-size dielectric elastomer actuators. When reducing the size of these actuators to below 1 cm, the ability to pattern the electrodes is adde ...
