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 ...

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 ...
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 ...
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 ...
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 ...

Tensegrity structures are spatial systems composed of tension and compression components in a self-equilibrated prestress stable state. Although the concept is over 60 years old, few tensegrity-based structures have been used for engineering purposes. Tens ...
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 ...
