Comparison of linear frequency and amplitude modulation for intraneural sensory feedback in bidirectional hand prostheses

Pablo Garcia del Valle, Edoardo D'Anna, Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Ivo Strauss, Giacomo Valle, Francesco Iberite

Recent studies have shown that direct nerve stimulation can be used to provide sensory feedback to hand amputees. The intensity of the elicited sensations can be modulated using the amplitude or frequency of the injected stimuli. However, a comprehensive c ...

Multisensory bionic limb to achieve prosthesis embodiment and reduce distorted phantom limb perceptions

Robin Mange, Bruno Herbelin, Olaf Blanke, Giulio Rognini, Javier Bello Ruiz, Silvestro Micera, Stanisa Raspopovic, Andrea Serino, Francesco Maria Petrini, Marco Solcà, Ivo Strauss, Giacomo Valle

Biomimetic Intraneural Sensory Feedback Enhances Sensation Naturalness, Tactile Sensitivity, and Manual Dexterity in a Bidirectional Prosthesis

Giulio Rognini, Edoardo D'Anna, Silvestro Micera, Francesco Maria Petrini, Ivo Strauss, Giacomo Valle, Francesco Iberite

Peripheral intraneural stimulation can provide tactile information to amputees. However, efforts are still necessary to identify encoding strategy eliciting percepts that are felt as both natural and effective for prosthesis control. Here we compared the n ...

Intrafascicular electrode implant

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini

An implantable device for intrafascicular stimulation and/or sensing of a peripheral nerve, including a blocking element adapted for wrapping a nerve, comprising an access point and an exit point, and an electrode adapted to traverse the blocking element v ...

A somatotopic bidirectional hand prosthesis with transcutaneous electrical nerve stimulation based sensory feedback

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Fiorenzo Artoni

According to amputees, sensory feedback is amongst the most important features lacking from commercial prostheses. Although restoration of touch by means of implantable neural interfaces has been achieved, these approaches require surgical interventions, a ...

On the Use of Intraneural Transversal Electrodes to Develop Bidirectional Bionic Limbs

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini

The development of more effective approaches for controlling dexterous hand prostheses is an important area of research currently addressed by several groups with the aim of improving the quality of life of amputees. It is particularly important to establi ...

Framework for the Development of Neuroprostheses: From Basic Understanding by Sciatic and Median Nerves Models to Bionic Legs and Hands

Stanisa Raspopovic, Francesco Maria Petrini, Marek Zelechowski, Giacomo Valle

Neuroprostheses based on electrical stimulation are becoming a therapeutic reality, dramatically improving the life of disabled people. They are based on neural interfaces that are designed to create an intimate contact with neural cells. These devices spe ...

Bidirectional Limb Neuro-Prosthesis

Silvestro Micera, Stanisa Raspopovic, Marco Bonizzato, Marco Capogrosso, Francesco Maria Petrini

Integrated closed-loop real-time limb neuro-prosthetic system comprising an artificial limb, a microprocessor, sensors, a signal conditioner, a stimulator, at least one EMG electrode and at least one sensory feedback electrode, characterized by the fact th ...

Intraneural stimulation elicits discrimination of textural features by artificial fingertip in intact and amputee humans

Fabrizio Vecchio, Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Fiorenzo Artoni

Restoration of touch after hand amputation is a desirable feature of ideal prostheses. Here, we show that texture discrimination can be artificially provided in human subjects by implementing a neuromorphic real-time mechano-neuro-transduction (MNT), which ...

Restoring Natural Sensory Feedback in Real-Time Bidirectional Hand Prostheses

Silvestro Micera, Stanisa Raspopovic, Marco Bonizzato, Marco Capogrosso, Francesco Maria Petrini, Jacopo Rigosa

Hand loss is a highly disabling event that markedly affects the quality of life. To achieve a close to natural replacement for the lost hand, the user should be provided with the rich sensations that we naturally perceive when grasping or manipulating an o ...
