Periodic Reporting for period 3 - IONOS (An iono-electronic neuromorphic interface for communication with living systems)
Periodo di rendicontazione: 2021-11-01 al 2023-04-30
(1) We have developped neuromorphic sensors for neural cells' activity recording based on iono-electronic materials. Passive and active sensors have been fabricated and charaterized for the recording of brain slices activity. Notably, we are currently exploring how organic materials can be used to create "plastic" sensors that could adapte to biological medium. We are also exploring how spatio-temporal sensing with dendritic like sensors can be used to process neural cells activity.
(2) We have put strong efforts for increasing the maturity level of neuromorphic hardware. In particular, we have developped a fully back end of line compatible process for memristive devices integration with CMOS. This work wil allow us to access to neuromorphic hardware for processing bio-signals. Such neuromorphic circuits are expected to reduce drastically energy consumption and to provide a large parallelism for time dependent signal processing.
Ultimately, innovative sensing approches will be coupled with neuromorphic hardware in order to demonstrate efficient communication in between artificial and biological medium.
