System-Level Design Considerations for Carbon Nanotube Electromechanical Resonators
Maher Kayal, Jean-Michel Sallese, Marc Pastre, Christian Kauth
Despite an evermore complete plethora of complex domain-specific semiempirical models, no succinct recipe for large-scale carbon nanotube electromechanical systems design has been formulated. To combine the benefits of these highly sensitive miniaturized m ...
Hindawi Publishing Corporation2013Optical Modulators Based on Microfabricated Tilting Flaps Operating at low Actuation Voltages
In this thesis the concept, modelling, design, fabrication process and characterization of novel optical modulators are presented. The devices consist of flaps exhibiting a large tilt with electrostatic actuation at low voltages. The applications comprise, ...
EPFL2012The need for speed
Herbert Shea, Samuel Rosset, Pit Gebbers
Development of dielectric elastomer actuators has been mainly targeted towards achieving giant static strain with little attention paid to their response speed, which can, depending on materials used, be as long as tens of seconds. However, most of the pra ...
SPIE2012Dielectric Elastomer Actuators for Microfluidics
Herbert Shea, Samuel Rosset, Luc Maffli
One of the goals of microfluidics is to bring a whole laboratory processing chain on a few square centimeters, Lab-On-Chips (LOC). But current LOCs require many heavy and power-consuming off-chip controls like pneumatics, pumps and valves, which keep the s ...
2012Large micromirror array for generating programmable slit masks for Multi-Object Spectroscopy
Nico de Rooij, Michael David Canonica, Wilfried Noell
Multi-object spectroscopy (MOS) is a powerful tool for space and ground-based telescopes for the study of the formation and evolution of galaxies. This technique requires a programmable slit mask for astronomical object selection. We are engaged in a Europ ...
Spie-Int Soc Optical Engineering2012Cutting the fat: Artificial muscle oscillators for lighter, cheaper, and slimmer devices
Artificial muscles based on dielectric elastomers show enormous promise for a wide range of applications and are slowly moving from the lab to industry. One problem for industrial uptake is the expensive, rigid, heavy and bulky high voltage driver, sensor ...
SPIE2012Piezoelectric Actuators Characterization
Pierre-André Farine, Alexis Boegli, Christian Robert, Patrick Stadelmann
This paper describes a system to drive piezoelectric actuators over more than one decade of voltages and one octave of frequencies, in order to perform high-speed complex impedance characterization at a user chosen voltage excitation level. This characteri ...
Ieee Computer Soc2012Thermal phase change actuator for self-tracking solar concentration
We present a proof of principle demonstration of a reversible in-plane actuator activated by focused sunlight, and describe a concept for its use as a self-tracking mechanism in a planar solar concentrator. By actuating at the location of focused sunlight ...
Optical Soc Amer2012Pump it up
Herbert Shea, Samuel Rosset, Luc Maffli
We report on the use of zipping actuation applied to dielectric elastomer actuators to microfabricate mm-sized pumps. The zipping actuators presented here use electrostatic attraction to deform an elastomeric membrane by pulling it into contact with a rigi ...
SPIE2012Lead-Free Relaxor-Like 0.75Bi0.5K0.5TiO3– 0.25BiFeO3 Ceramics with Large Electric Field-Induced Strain
Dense and phase-pure ferroelectric ceramics of 75 mol.% Bi0.5K0.5TiO3 - 25 mol.% BiFeO3 are prepared by the conventional solid state reaction method. Their crystal structure is analyzed and discussed. The dielectric and piezoelectric properties of the cera ...
