MEM-BRAIN: MEMristor synapses for BRAIN computing

In the context of this project, we applied the principles of neuromorphic computing to the classification of EMG signals, proposing an innovative approach to prostheses control. Although the market already provides high-tech solutions in fact, the process of adapting industry-standard prostheses to patients is nowadays complex and lengthy. For some aspects, it can be said that it is the patient the one demanded to learn how to use the prosthesis in an appropriate manner, rather than simply having a prosthesis capable of responding naturally to the patient.
In this context, our solution tries to shift the paradigm: exploiting the learning capabilities of a neural network, we propose an adaptive prosthesis control, capable of responding to the patient after a preliminary training phase lasting only 15 minutes.
In this summary, we briefly review the process we followed during the design of the solution, describing our work in relation to both the growing interest in neuromorphic computing and the requirements we received from partner institutions. Moving from a study of state of the art approaches to neural networks, we studied the efficiency and the feasibility of implementations using memristors as circuital components. We also proposed a new process of memristor production using inorganic (TiO2) and nanocomposite polymer matrix-based materials.
Our research on the topic of memristors production has been published and presented at the Nanotech World Techconnect conference in the cities of Washington D.C. and Birmingham. As far as the research on neuromorphic computing and learning algorithms is concerned, our work has been presented at Nonlinear Dynamics in Computational Neuroscience: from Physics and Biology to ICT conference in Turin, and we also succeeded in the implementation of a working prototype of the proposed solution.
