  Description du sujet:
• Ultra-flexible, conformable and implantable organic electronic devices incorporating artificial intelligence promise to revolutionize real-time monitoring and treatment of chronic diseases. Such devices could be based on organic electrochemical transistors (OECTs) exploiting mixed ion-electron polymer conductors (PMIECs) as active layers. Indeed, PMIECs have emerged as an excellent hardware platform for interfacing biology with conventional electronics; identified as the "organic or plastic bioelectronics" field. The organic electrochemical transistor (OECTs) is considered one of the key elements to make such transduction. Its efficiency is evaluated through few Figures of Merit (FoM): i) transconductance (gm), ii) switching times (ionic vs. electronic), iii) in situ imaging of the dedoping propagation front ( for example, measurement of ionic mobility), iv) the electrochemical impedance to establish the equivalent electrical circuit and extract the capacitance. Beyond these physico-chemical properties, our current understanding demonstrated short and long-term potentiation and depreciation, as well as pair-pulsed facilitation (PPF), properties in OECTs in order to elaborate organic synapse-like behavior. Indeed, the state-of-the-art has shown the realization of 2D crossbar architectures based on ElectroChemical (EC)-RAM-like devices. Nonetheless, measurements were done under non-atmospheric conditions. Moreover, the PMIECs were not enough investigated to offer the most reliable properties. This PhD project is embedded in an european consortium dealing with the synthesis of new PMIECs architecture and the understanding of PMIECs structure-property relationship by spectroscopic investigations _in-situ_ & _operando_ OECTs, in order to develop organic neuromorphics circuits.-
