Sviluppo di Dispositivi Bioelettronici Intelligenti per Interfacce Neuronali di Nuova Generazione

The aim of the project is to study and develop devices for the realization of a prototype intelligent EEG based on the use of OETs and memristor, and validate it against current higher-performing systems. To do this, the knowledge and expertise within the Parma offices of IMEM and IN (CNR Institute for Neuroscience) must be integrated into a joint, multi-year project.

IMEM and IN will extend the technologies developed by IMEM for the detection and study of EEG signals, opening up new perspectives for the use of these signals under ethological conditions. It is important to note that, since they are essentially organic polymer devices, they offer ideal physiological compatibility conditions. IMEM will study and develop the integration of "memristivi" systems (memories that are both physical with logic) in sensors to obtain a new class of ultra-high sensitivity and "smart" electrodes that will open up new perspectives in the classification of signals at the hardware level, making signal detection faster and possibly "real-time", a fundamental requirement in human-machine interactions.

In the context of applied neuroscience, it is very important to create systems that can anticipate the motor intention of the subject and thus predict his actions. The basic technique used is high-density electroencephalographic (EEG) recording integrated with electromiographic (EMG) and accelerometric recording (position sensors). The set of three techniques allows you to describe the neural activity of subjects whose motor activity is monitored with temporal resolution of the order of millisecond. The aim of the project is to develop an innovative predictive system that can be used not only in laboratory conditions, but also in natural situations.

Technologies developed by IMEM, based on electrochemical devices and systems, will be optimized for the detection and study of EEG signals, opening up new perspectives for the use of these signals in ethological conditions. Using essentially organic polymer devices, they offer ideal physiological compatibility conditions. IMEM will study and develop the integration of "meristivi" systems into sensors to achieve a new class of ultra-high-sensitivity and "smart" electrodes
