Soft flexion sensors integrating strechable metal conductors on a silicone substrate for smart glove applications

Joan Teixidor, Stéphanie Lacour, Hadrien Olivier Michaud

We design and implement a sensory skin that monitors in real time finger flexure (three sensors per finger) of a user's hand. Compared to current technologies, the electronic skin is made entirely of stretchable materials integrating silicone rubber, low r ...

Conducting polymer electrodes for auditory brainstem implants

Amélie Anne Guex, Nicolas Vachicouras, Stéphanie Lacour

The auditory brainstem implant (ABI) restores hearing in patients with damaged auditory nerves. One of the main ideas to improve the efficacy of ABIs is to increase spatial specificity of stimulation, in order to minimize extra-auditory side-effects and to ...

Chronic multichannel neural recordings from soft regenerative microchannel electrodes during gait

Sophie Marie Marthe Wurth, Shreya Narasimhan, Stéphanie Lacour, Katherine Marie Musick, Silvestro Micera, Marco Capogrosso, Jacopo Rigosa

Reliably interfacing a nerve with an electrode array is one of the approaches to restore motor and sensory functions after an injury to the peripheral nerve. Accomplishing this with current technologies is challenging as the electrode-neuron interface ofte ...

Elastomeric Electronic Skin for Prosthetic Tactile Sensation

Stéphanie Lacour, Hadrien Olivier Michaud, Aaron Powers Gerratt

This report demonstrates a wearable elastomer-based electronic skin including resistive sensors for monitoring fi nger articulation and capacitive tactile pressure sensors that register distributed pressure along the entire length of the fi nger. Pressure ...

Extracellular matrix components in peripheral nerve repair: how to affect neural cellular response and nerve regeneration?

Stéphanie Lacour, Alba Carla De Luca

Peripheral nerve injury is a serious problem affecting significantly patients' life. Autografts are the "gold standard" used to repair the injury gap, however, only 50% of patients fully recover from the trauma. Artificial conduits are a valid alternative ...

Corticospinal neuroprostheses to restore locomotion after spinal cord injury

José del Rocio Millán Ruiz, Stéphanie Lacour, Silvestro Micera, Grégoire Courtine, Nikolaus Wenger, Ivan Rusev Minev, Marco Bonizzato, Janine Beauparlant, Eduardo Martin Moraud, Pavel Musienko, David Allenson Borton

In this conceptual review, we highlight our strategy for, and progress in the development of corticospinal neuroprostheses for restoring locomotor functions and promoting neural repair after thoracic spinal cord injury in experimental animal models. We spe ...

Hybrid stretchable circuits on silicone substrate

Stéphanie Lacour

When rigid and stretchable components are integrated onto a single elastic carrier substrate, large strain heterogeneities appear in the vicinity of the deformable-non-deformable interfaces. In this paper, we report on a generic approach to manufacture hyb ...

Stretchable capacitive tactile skin on humanoid robot fingers - first experiments and results

Aude Billard, Nicolas Sommer, Stéphanie Lacour, Aaron Powers Gerratt

A stretchable tactile sensor skin has been demonstrated on the dorsal side of a robotic hand for the first time. The sensors can detect normal pressures on the same scale as human skin but also in excess of 250 kPa and withstand strains in excess of 15%. U ...

Extremely robust and conformable capacitive pressure sensors based on flexible polyurethane foams and stretchable metallization

Douglas Cameron Watson, Stéphanie Lacour, Hugues Vandeparre

Microfabricated capacitive sensors prepared with elastomeric foam dielectric films and stretchable metallic electrodes display robustness to extreme conditions including stretching and tissue-like folding and autoclaving. The open cellular structure of the ...

A Microchannel Neuroprosthesis for Bladder Control After Spinal Cord Injury in Rat

Stéphanie Lacour, Katherine Marie Musick, Ivan Rusev Minev

A severe complication of spinal cord injury is loss of bladder function (neurogenic bladder), which is characterized by loss of bladder sensation and voluntary control of micturition (urination), and spontaneous hyperreflexive voiding against a closed sphi ...

PDMS Microchannel Regenerative Peripheral Nerve Interface

Stéphanie Lacour, Katherine Marie Musick

We have fabricated a soft silicone structure to support the regeneration of a sciatic nerve. The device consists of 70 parallel (120 x 110 mu m(2)) channels through which axons extend and then reconnect to the muscles on the other side of the device. Throu ...

Hyper-flexible 1-D shape sensor

Dario Floreano, Michal Karol Dobrzynski, Ramon Pericet Camara, Géraud L'Eplattenier, Stéphanie Lacour

Here we describe a sensor capable of perceiving complex one-dimensional (1-D) shape of an underlying substrate in a static and dynamic manner. The sensor consists of seven, serially connected, hyper-flexible strain gauges, manufactured using stretchable-go ...

Elastomeric substrates with embedded stiff platforms for stretchable electronics

Stéphanie Lacour, Alessia Romeo

Stretchable electronics typically integrate hard, functional materials on soft substrates. Here we report on engineered elastomeric substrates designed to host stretchable circuitry. Regions of a stiff material, patterned using photolithography, are embedd ...
