Planar micro-direct methanol fuel cell prototyped by rapid powder blasting

We present a planar micro-direct methanol fuel cell (μ−DMFC) fabricated by rapid prototyping powder blasting technology. Using an elastomeric mask, we pattern two parallel microfluidic channels in glass. The anode and cathode of the fuel cell are formed by ...

HandCARE: a cable-actuated rehabilitation system to train hand function after stroke

Thomas Maeder, Roger Gassert, Etienne Burdet, Olivier Lambercy, Ludovic Dovat

We have developed a robotic interface to train hand and ﬁnger function. HandCARE is a Cable-Actuated REhabilitation system, in which each ﬁnger is attached to an instrumented cable loop allowing force control and a predominantly linear displacement. The de ...

A 2-DOF fMRI compatible haptic interface to investigate the neural control of arm movements

Hannes Bleuler, Roger Gassert, Dominique Chapuis, Etienne Burdet, Olivier Lambercy, Ludovic Dovat, Yves Ruffieux

This paper describes a two-degrees-of-freedom haptic interface to investigate the brain mechanisms of human motor control, which is capable of safely and gently interacting with human arm motion during functional magnetic resonance imaging (fMRI). A hydros ...

Actuation Methods for Applications in MR Environments

Hannes Bleuler, Roger Gassert, Dominique Chapuis, Etienne Burdet, Ludovic Dovat

The choice of an adequate actuation method is a central issue in the development of any mechatronic device and strongly determines the dynamic performances of the system. This choice is particularly difficult for robotic systems working within a magnetic r ...

Multi-Joint Arm Movements to Investigate Motor Control with fMRI

Hannes Bleuler, Roger Gassert, Etienne Burdet, Ludovic Dovat

Performing multi-joint arm movements in controllable dynamic environments during functional magnetic resonance imaging (fMRI) could provide important insights into the brain mechanisms involved in human motor control and related dysfunctions. In order to o ...
