Dielectric Elastomer Actuators for soft-grasping

Dario Floreano, Herbert Shea, Samuel Rosset, Jun Shintake, Bryan Edward Schubert

We demonstrate here a configuration of soft actuator which has several features such as, being completely soft, simple, thin, foldable, and stretchable while having uni/bidirectional bending actuation. Theoretically the actuation can be extended to multidi ...

Optimal design of a squeeze film actuator for friction feedback

Yves Perriard, Yoan René Cyrille Civet, Christophe Winter

Sense of touch belongs to one of the five Human Senses. Whereas blind people largely use feeling in everyday life, sighted person mainly focus on hearing and vision. However, haptic interface started being introduced in customers applications, such as smar ...

More than 10-fold increase in the actuation strain of silicone dielectric elastomer actuators by applying prestrain

Herbert Shea, Samuel Rosset, Samin Akbari

Silicone based dielectric elastomer actuators are preferred for reliable and fast actuation due to their negligible viscoelastic behavior. However, it is more challenging to achieve large deformation actuation using this class of polymers compared to the t ...

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 ...

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 ...

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 ...

Large Hybrid High Precision MEMS Mirrors

Dara Zaman Bayat

This thesis presents the design and microfabrication technology of a tip-tilt, 2 degree of freedom "mirror system" made out of Silicon On Insulator (SOI) wafers with two movable mirrors that have diameter of 10 mm. The system was intended for precise beam ...
