Optically-transparent actuators and micro-mechanical systems fabricated using femtosecond lasers

Yves Bellouard, Tao Yang

Non-linear laser-matter interaction offers the possibility to structure transparent material in three dimensions. Here, we demonstrate that such process can be implemented for fabricating novel type of microsystems, including actuators transparent to visib ...

A transformable tensegrity-footbridge system

Ian Smith, Landolf-Giosef-Anastasios Rhode-Barbarigos, Nizar Bel Hadj Ali, Nicolas Willy Veuve, René Motro

Tensegrity structures are self-stressed pin-jointed structures composed of cables and struts. They are advantageous systems for transformable applications since structural elements and active elements can be combined. A transformable “hollow-rope” tensegri ...

Self-sensing dielectric elastomer actuators in closed-loop operation

Herbert Shea, Samuel Rosset

Because of their large output strain, dielectric elastomer actuators (DEAs) have been proposed for tunable optics applications such as tunable gratings. However, the inherent viscoelastic drift of these actuators is an important drawback and closed-loop op ...

Linear multi-modal actuation through discrete coupling

Nitesh Maheshwari

Due to technological limitations robot actuators are often designed for specific tasks with narrow performance goals, whereas a wide range of output and behaviours is necessary for robots to operate autonomously in uncertain complex environments. We presen ...

The 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 ...

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 ...

Microsystems and Sensors

Yves Bellouard

In this chapter, the use of femtosecond laser to fabricate glass-based microsystems and sensors is examined. Several advanced technology demonstrators are presented, including some very unusual fused silica MEMS. Present technological barriers are discusse ...
