Evaluation of MR-Compatibility of Electrostatic Linear Motor

Hannes Bleuler, Roger Gassert, Laurent Sache

This paper reports a new MRI (Magnetic Resonance Imaging) compatible actuator that can operate near an MRI without degrading its imaging quality. A high-power electrostatic motor is introduced and its MR-compatibility is examined, both experimentally and t ...

Influence of force and torque feedback on operator performance in a VR-based suturing task

Hannes Bleuler, Roger Gassert, Ricardo Daniel Rita Beira, Ali Sengül, Laura Santos Carreras

The introduction of Minimally Invasive Surgery (MIS) has revolutionised surgical care, considerably improving the quality of many surgical procedures. Technological advances, particularly in robotic surgery systems, have reduced the complexity of such an a ...

Neurological and Robot-Controlled Induction of an Apparition

Olaf Blanke, Hannes Bleuler, Bruno Herbelin, Andrea Serino, Giulio Rognini, Roy Salomon, Lukas Heydrich, Polona Pozeg

Tales of ghosts, wraiths, and other apparitions have been reported in virtually all cultures. The strange sensation that somebody is nearby when no one is actually present and cannot be seen (feeling of a presence, FOP) is a fascinating feat of the human m ...

Control of a Haptic Interface and a Micromachining Setup with an Open Source Real-Time System

Hannes Bleuler, Rolf Wüthrich, Evren Samur, Ulrich Spälter, Lionel Flaction

Open source software have evolved into powerful tools for real-time control of mechatronic systems. They are of interest for academic purposes, as they promise high flexibility at low cost. In this paper, we investigate the performance of an open source co ...

Experimental Evaluation of a Haptic Interface for Endoscopic Simulation

Hannes Bleuler, Evren Samur, Lionel Flaction

The main goal of virtual reality based surgery simulators with haptic feedback is to provide an alternative to traditional training methods on animals, cadavers or real patients. Haptic feedback is a key feature for every surgery simulator for the training ...

Design and Control of a novel Thermo-tactile Multimodal Display

Hannes Bleuler, Simon Gallo

This paper describes the design and control of a water-based multimodal haptic display. The system is able to provide temperature and pressure (pulse) cues through a finger-sized display. Temperature feedback is obtained by mixing hot and cold water stored ...

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

Hannes Bleuler, Roger Gassert, Dominique Chapuis

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 ...

Quantifying the role of motor imagery in brain-machine interfaces

Olaf Blanke, Hannes Bleuler, Andrea Serino, Michela Bassolino, Silvia Marchesotti

Despite technical advances in brain machine interfaces (BMI), for as-yet unknown reasons the ability to control a BMI remains limited to a subset of users. We investigate whether individual differences in BMI control based on motor imagery (MI) are related ...

Extending the body to virtual tools using a robotic surgical interface: evidence from the crossmodal congruency task

Olaf Blanke, Hannes Bleuler, Giulio Rognini, Jane Aspell, Michiel van Elk, Ali Sengül

The effects of real-world tool use on body or space representations are relatively well established in cognitive neuroscience. Several studies have shown, for example, that active tool use results in a facilitated integration of multisensory information in ...

Characterization of Surface Cracks Through The Local Magnetic Field Induced by Eddy Currents

Hannes Bleuler, Marco Picasso, Pavel Kejik, Roland Moser, David Florian Hippert

It is important to reliably characterize cracks in metallic mechanical parts in order to assess the serenity of damage due to fatigue. The most important parameter for this is the crack depth. This is notoriously difficult with standard Eddy current techni ...

The current signal in Spark Assisted Chemical Engraving (SACE), what does it tell us ?

Hannes Bleuler, Rolf Wüthrich, Ulrich Spälter

Spark-assisted chemical engraving (SACE) is a promising micro-machining technology for the low-cost machining of holes and channels in non-conducting materials, such as glass and some ceramics. Despite the complexity of SACE due to the interdependency of t ...

Design and Psychophysical Evaluation of a Tactile Pulse Display for Teleoperated Artery Palpation

Hannes Bleuler, Philippe Rétornaz, Roger Gassert, Laura Santos Carreras

During traditional open procedures, surgeons directly palpate tissues before dissecting them. In this way, they can avoid the accidental damage of hidden arteries that can lead to fatal hemorrhage. New Minimally Invasive Surgical (MIS) techniques progressi ...

Torso-mounted Vibrotactile Interface to Experimentally Induce Illusory Own-body Perceptions

Olaf Blanke, Hannes Bleuler, Giulio Rognini

Recent developments in virtual reality and robotic technologies have allowed investigating the behavioural and brain mechanisms that grounds self-consciousness in the multisensory (e.g. vision and touch) and sensorimotor processing of bodily signals. Yet, ...

New horizons for patient safety: LIGRA (LIfe Guard for Robotic surgery Assistance) An interactive platform centralizing information and control in robotic surgery Operating Rooms

Hannes Bleuler

The present paper describes LIGRA, an innovative technological solution developed in the context of the SAFROS co-funded EU project. Its general goal is to improve patient safety during minimal invasive robotic surgery. Focusing on the risks introduced in ...

Development of a Microsurgery Training System

Hannes Bleuler

Surgeons require significant training to acquire sufficient dexterity and hand-eye coordination to manipulate objects skilfully under the microscope. This paper presents a computer-based real-time simulation of microsurgery as well as the hardware setup. I ...

A Real-Time Simulator for Interventional Radiology

Hannes Bleuler, Evren Samur, Lindo Robert Duratti

Interventional radiologists manipulate guidewires and catheters and steer stents through the patient’s vascular system under X-ray imaging for treatment of vascular diseases. The complexity of these procedures makes trainingmandatory in order to master han ...
