Brain network modulation in transradial amputee with finger perception restored through biomimetic intraneural stimulation

Fabrizio Vecchio, Silvestro Micera, Giacomo Valle

Introduction/aims The hand is a sophisticated tool which allows humans to interact with the external world mainly via the sense of touch. Previous evidences demonstrated that electrical stimulations of the nerve trunks governing the hand are able to restor ...

Morphological Neural Computation Restores Discrimination of Naturalistic Textures in Trans-radial Amputees

Fabrizio Vecchio, Silvestro Micera, Francesco Maria Petrini, Ivo Strauss, Giacomo Valle, Roberto Puddu, Simone Romeni

Humans rely on their sense of touch to interact with the environment. Thus, restoring lost tactile sensory capabilities in amputees would advance their quality of life. In particular, texture discrimination is an important component for the interaction wit ...

Brain reactions to the use of sensorized hand prosthesis in amputees

Fabrizio Vecchio, Edoardo D'Anna, Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Ivo Strauss, Giacomo Valle, Francesco Iberite

Objective We investigated for the first time the presence of chronic changes in the functional organization of sensorimotor brain areas induced by prolonged training with a bidirectional hand prosthesis. Methods A multimodal neurophysiological and neuroima ...

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 ...

Integrated packaging solutions and hotplates for a miniature atomic clock and other microsystems

Fabrizio Vecchio

This thesis aimed at developing innovative packaging solutions for a miniature atomic clock and other microsystems in the cm-scale, i.e. somewhat larger than what is practical for full "chip-scale" device-package integration using clean-room technologies f ...

Effects of Thermal Losses on the Heating of a Multifunctional LTCC Module for Atomic Clock Packaging

Thomas Maeder, Peter Ryser, Fabrizio Vecchio, Conor Joseph Slater

An innovative multifunctional LTCC module has been designed for miniature atomic clock packaging. The components of miniature atomic clocks need to be efficiently packaged and connected to each other, and a precise temperature control is required for them. ...
