Design of an Innovative Cylindrical Spring with a Negative Stiffness

Yves Perriard, Yoan René Cyrille Civet, Jonathan André Jean-Marie Chavanne

Interest in the dielectric electroactive polymer is growing in the medical field because of the large similarity with the biological muscles. With the objective to create an artificial pump based on DEAP, this paper presents the concept of an innovative sp ...

Parametric study of Pneumatic Circuit Model for Powering and Controlling Soft Pneumatic Actuators

Jamie Paik, Sagar Dattatray Joshi

Soft pneumatic actuator (SPA) based devices often use heuristic approaches for designing the power and control system, which are not necessarily optimized for the application. Especially in portable applications, due to constraints on the overall size and ...

Sensorless Method with Parameter Identification Applied to a Bistable Fast Linear Switched Reluctance Actuator for Textile Machine

Yves Perriard, Douglas Martins Araujo, Faguy Tamwo Simo

This paper provides a sensorless method to control the position of keys passing through a linear actuator used in an industrial textile machine. The presented method describes how to find out the position of the key using two cascading discrete Kalman filt ...

Series Elastic Actuation for Assistive Orthotic Devices: Case Study of Pneumatic Actuator

Hannes Bleuler, Mohamed Bouri, Jonathan Olivier, Amalric Louis Ortlieb

Wearable assistive robotics is a modern field where intelligent actuated systems work in collaboration with the body to replace a lost limb, to enhance performances (e.g. carrying load, walking, running, jumping) or to train or rehabilitate specific activi ...

Monolithic transparent 3D dielectrophoretic micro-actuator fabricated by femtosecond laser

Yves Bellouard, Tao Yang

We demonstrate a three-dimensional (3D) monolithic micro-actuator fabricated by non-ablative femtosecond laser micromachining and subsequent chemical etching. The actuating principle is based on dielectrophoresis. An analytical modeling of this actuation s ...

Injection Device

Yves Perriard, Romain David Besuchet

An injection deviee for injecting injection material, comprising: an elastic deformable element (3) able to exert a pushing force on a piston (20) of a syringe (2) so as to eject a quantity of injection material out of the syringe (2); a stopper ( 4) for r ...
