Abstract:

To realize the future brain-machine interfaces, amounts of efforts have been made to develop electronics that mainly work on two aspects: brain-activity detections and brain-function imitations. Organic electrochemical transistors (OECTs), as a member of organic electronics, are able to realize both functions of signal readout from the brain and mimicking neural systems, owing to its ionic-electronic mixing characteristic and outstanding signal amplification capability. This talk will introduce how OECTs play roles in the development of brain-machine interface, discuss the state-of-art achievements and major hindrances, and propose possible approaches to enhancing the capability of OECTs for brain-machine interactions from views of material and device understandings.
