Restoring Motor Functions After Stroke: Multiple Approaches and Opportunities

Friedhelm Christoph Hummel, Estelle Emeline Raffin

More than 1.5 million people suffer a stroke in Europe per year and more than 70% of stroke survivors experience limited functional recovery of their upper limb, resulting in diminished quality of life. Therefore, interventions to address upper-limb impair ...

Gravity-Insensitive Flexure Pivot Oscillators

Simon Nessim Henein, Ilan Vardi, Etienne Frédéric Gabriel Thalmann, Mohammad Hussein Kahrobaiyan, Lennart Rubbert

Classical mechanical watch plain bearing pivots have frictional losses limiting the quality factor of the hairspring-balance wheel oscillator. Replacement by flexure pivots leads to a drastic reduction in friction and an order of magnitude increase in qual ...

Increasing upper limb training intensity in chronic stroke using embodied virtual reality: a pilot study

Olaf Blanke, José del Rocio Millán Ruiz, Andrea Serino, Gangadhar Garipelli, Thomas Schmidlin, Odile Hélène Chevalley

Background: Technology-mediated neurorehabilitation is suggested to enhance training intensity and therefore functional gains. Here, we used a novel virtual reality (VR) system for task-specific upper extremity training after stroke. The system offers inte ...

Bipolar Lightning Flashes Observed at the Säntis Tower: Do We Need to Modify the Traditional Classification?

Farhad Rachidi-Haeri, Marcos Rubinstein, Mario Paolone, Davide Pavanello, Mohammad Azadifar

We present and discuss current waveforms associated with 13 bipolar lightning flashes recorded at the Santis Tower during the period from June 2010 to January 2015. During this period, a total of 427 flashes were recorded, of which 13 (3%) were classified ...

Design of a Miniature Short-Stroke Constant-Force Linear Actuator

Yves Perriard, Romain David Besuchet

This paper presents the modelling, design and testing of a short-stroke linear actuator to be embedded in a battery-powered positioning device. The particularity of this small (1 cm3) electromagnetic actuator is that it has to provide a constant force alon ...

Self-sensing dielectric elastomer actuators in closed-loop operation

Herbert Shea, Samuel Rosset

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 ...
