DEyeA: Artificial Muscles for the Restoration of Eye Blinking Following Facial Paralysis

Yves Perriard, Yoan René Cyrille Civet, Stefania Maria Aliki Konstantinidi, Amine Benouhiba

Facial nerve palsy results in the inability to control facial muscles, including the Orbicularis Oculi, which is the main muscle enabling the blinking action. Blinking is not only important for responding socially to other humans, it is also essential for ...

Towards Development of a Novel Variable Stiffness Instrumented Gripper

Yves Perriard, Bhawnath Tiwari, Marjan Ghorbani, Dan Cisier

The need for the gripper becomes more demanding when it comes to automated manipulation or handling of fragile structures. Depending on the object and the task requirements, a single gripper with a fixed stiffness may not be enough, and a variable mechanis ...

Design of an Optimized Self-Sensing Piezoelectric Cantilever for Micro-Robotic Applications

Yves Perriard, Louis Antoine Masson

Quasi-static piezoelectric actuators are used in micro-robotics due to the small displacements they can achieve, and they have been proved suitable for Self-Sensing Actuation (SSA) applications. The fabrication parameters of an actuator (i.e. morphology, s ...

An Experimental Approach for the Design of Uni-axial Fiber Reinforced Dielectric Elastomer Actuators

Julian Asboth, Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Stefania Maria Aliki Konstantinidi, Armando Matthieu Walter, Simon Holzer

Dielectric Elastomer Actuators (DEAs) are a type of soft actuators, generating mechanical displacement when an electric stimulation is applied. DEAs can be described as compliant capacitors, and when a voltage is applied, a compressive Maxwell stress will ...

Potential of Flex-PCB Winding in Coreless Tubular Permanent Magnet Synchronous Machines

Yves Perriard

Many applications are limited by the performance of the motors that power them. In the small power range, slotless BLDC motors are commonly used due to their intrinsic high power density and smooth torque characteristic. However, recent work has shown that ...

Contact Tip Trajectory in Steady-State Regime Prediction Using Deep Learning for Piezoelectric Actuators

Yves Perriard, Paolo Germano, Marjan Ghorbani, Xinxin Liao, Marc Michel Charles Favier

Including friction modeling in simulation can be challenging and requires time domain simulation, which is time consuming. We propose to separate the friction modelling from the FEA (Finite Element Analysis). The approach is defined for UCM (Ultrasonic Cer ...
