Overview

Objectives

The goal of this activity the development of spiking skin for sensory feedback on prosthetic devices. The fellow will first evaluate the properties of different transduction methods amenable to spiking implementation and their fit to the needs of the prosthetic application, starting from the characterization of a skin prototype integrated on iLimb (Ossur, previously developed by UNIBI). A novel methodology based on printed nanowires on flexible substrates will be then used to develop neural nanowire FET and memristor assemblies. This technique will be then used to develop functional neural element devices and components via modelling and practical fabrication. The in-depth investigation will involve the heterogeneous integration of circuits on flexible substrates, printing of neural nanowire FET based circuits with well controlled print dynamics, electro-mechanical characterization and modeling. Custom contact print set up will be used to fabricate neural nanowire FETs circuits based neural backplane. The resulting neuromorphic flexible large area skin will be integrated and validated on prosthetic devices

Expected Results

ESR8 will go beyond the current state of the art by developing large area printable neuromorphic nanowire based backplane circuits for e-skin, and integrating it on prosthetic devices. The flexible skin will be designed in a way that it can be used in the fingertips (high resolution for manipulation) but also on large areas, to cover most of the prosthesis.

João Neto

Since I joined university i knew that nanotechnologies was the path to follow. The possibilities of creating life-changing technology are immense and i am especially interested in the field of flexible and transparent electronics. By using nanomaterials like nanowires, flexible devices can be fabricated for a variety of applications and during my master thesis i aligned nanowires in a large-scale way that led to my work on this project.

Neutouch for me

It is a great opportunity to combine my nanofabrication and flexible electronics background with neuroscience, providing sensory feedback on prosthesis is a very ambitious and fulfilling challenge that will have a great impact on our society.
