An organic electrochemical transistor for multi-modal sensing, memory and processing

Abstract By integrating sensing, memory and processing functionalities, biological nervous systems are energy area efficient. Emulating such capabilities in artificial is, however, challenging is limited by the device heterogeneity of sensing cores. Here we report an organic electrochemical transistor capable processing. The has a vertical traverse architecture crystalline–amorphous channel that can be selectively doped ions to enable two reconfigurable modes: volatile receptor non-volatile synapse. As receptor, multi-modal responsive stimuli as light. synapse, it 10-bit analogue states, low switching stochasticity good state retention. We also show homogeneous integration devices could provide functions conditioned reflexes used for real-time cardiac disease diagnoses via reservoir computing.
