Neural signatures of visuo-motor integration during human-robot interactions

Olaf Blanke, Hannes Bleuler, Giulio Rognini, Fosco Bernasconi, Silvia Marchesotti

Visuo-motor integration shapes our daily experience and underpins the sense of feeling in control over our actions. The last decade has seen a surge in robotically and virtually mediated interactions, whereby bodily actions ultimately result in an artifici ...

Fabrication of metallic nanoparticles by electrochemical discharges

Hannes Bleuler, Ashwin Lal

A method for the fabrication of metallic nanoparticles in large quantities by electrochemical discharges is presented. In an aqueous electrolyte, large current density (similar to 1 A/mm(2) at similar to 20 V) leads to the formation of a 'gas film' around ...

Actuation Methods for Applications in MR Environments

Hannes Bleuler, Roger Gassert, Dominique Chapuis

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 ...

A Computer-Based Real-Time Simulation of Interventional Radiology

Hannes Bleuler, Evren Samur, Ulrich Spälter, Lindo Robert Duratti

Interventional radiology is a minimally invasive procedure where thin instruments, guidewires and catheters or stents are steered through the patient’s vascular system under X- ray imaging for treatment of vascular diseases. The complexity of these procedu ...

Cy-mag3D: a simple and miniature climbing robot with advance mobility in ferromagnetic environment

Francesco Mondada, Hannes Bleuler, Frédéric Rochat, Patrick Schoeneich

Cy-mag3D is a miniature climbing robot with advanced mobility and magnetic adhesion. It is very compact: a cylindrical shape with 28 mm of diameter and 62 mm of width. Its design is very simple: two wheels, hence two degrees of freedom, and an advanced mag ...

Gait pattern prediction via bilateral neural ensemble recordings in motor cortex in rats

Hannes Bleuler, Solaiman Shokur, Miguel Nicolelis

We are interested in developing and building an experimental system for controlling a quadruped robot with a brain-derived signal of a rat. We recorded large ensembles of neurones in left M1 and right M1 and S1 using chronically implanted multi-electrodes ...

Generic and Systematic Evaluation of Haptic Interfaces Based on Testbeds

Hannes Bleuler, Evren Samur, Ulrich Spälter

The purpose of evaluation procedures is to achieve both qualitative and quantitative statements on haptic rendering realism and performance. Since a haptic interface provides an interaction between a user and a virtual environment, fidelity of a haptic int ...

Passive diamagnetic contactless suspension rotor with electrostatic glass motor

Hannes Bleuler

In this work, we introduce a newly developed passive and frictionless diamagnetic contactless suspension rotor with electrostatic glass motor. A 20 mm diameter disc-shaped rotor comprised of pyrolytic graphite with glass is fabricated. The rotor is diamagn ...

Study of polyvinylidene fluoride (PVDF) based bimorph actuators for laser scanning actuation at kHz frequency range

Hannes Bleuler, Ricardo Pérez Suárez

This work focuses on some promising applications of polyvinylidene fluoride (PVDF) based bimorph actuators in microengineering. The actuator of several centimeters in length and 100 mu m in thickness takes advantage of the structural and electromechanical ...

Bubble evolution on a vertical electrode under extreme current densities

Christos Comninellis, Hannes Bleuler, Rolf Wüthrich

Under gas evolution, the current voltage characteristics of an electrochemical cell are strongly affected by the presence of growing bubbles. At high current densities, the evolution of the bubbles becomes the rate limiting step of the electrochemical proc ...

A flexible multimodal tactile display for delivering shape and material information

Hannes Bleuler, Simon Gallo

The growing complexity of telemanipulation tasks calls for increased realism and intuitiveness of the interaction between the user and the master control. Humans perceive multiple haptic features of an object such as its stiffness, temperature, and shape, ...

Haptic/VR Assessment Tool for Fine Motor Control

Hannes Bleuler, Roger Gassert, Evren Samur

The Nine Hole Peg Test (NHPT) is routinely used in clinical environments to evaluate a patient’s fine hand control. A physician measures the total time required to insert nine pegs into nine holes and obtains information on the dexterity of the patient. Ev ...

Congruent Visuo-Tactile Feedback Facilitates the Extension of Peripersonal Space

Olaf Blanke, Hannes Bleuler, Michiel van Elk, Ali Sengül

Effective tool use relies on the integration of multisensory signals related to one's body and the tool. It has been shown that active tool use results in an extension of peripersonal space, i. e., the space directly surrounding the human body. In the pres ...

The High-Resolution Magnetic Camera: A Novel Sensor for Eddy Current Testing

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

Eddy current techniques are often used to detect and, in some advanced applications, to characterize fatigue surface-breaking cracks appearing in mechanical parts. One of the major difficulties in this approach is to reliably separate the crack contributio ...

Expanding the primate body schema in sensorimotor cortex by virtual touches of an avatar

Hannes Bleuler, Solaiman Shokur, Miguel Nicolelis

The brain representation of the body, called the body schema, is susceptible to plasticity. For instance, subjects experiencing a rubber hand illusion develop a sense of ownership of a mannequin hand when they view it being touched while tactile stimuli ar ...

Screening of the factors influencing frictional interactions between a cylindrical tip and the cardiac wall using factorial analysis

Bandar Muntazar Hakim, Hannes Bleuler, Giulio Rognini, Lionel Flaction

Knowledge of frictional forces acting on the tips of minimally invasive medical devices is important in the design and simulation of such devices. Moreover, several studies have shown that uncontrolled frictional forces can induce damage to organs. The goa ...

Design and Evaluation of a Novel Haptic Interface for Endoscopic Simulation

Hannes Bleuler, Evren Samur, Lionel Flaction

Inspection of the colon with an endoscope for early signs of cancer (colonoscopy) has become an extremely widespread procedure, since early treatment radically improves the outlook of patients. The procedure requires a close coordination between the sense ...

Visuo-tactile integration and body ownership during self-generated action

Olaf Blanke, Hannes Bleuler, Roy Salomon, Giulio Rognini, Jane Aspell, Ali Sengül

Although there is increasing knowledge about how visual and tactile cues from the hands are integrated, little is known about how self-generated hand movements affect such multisensory integration. Visuo-tactile integration often occurs under highly dynami ...
