Neuromorphic Organic Devices (NODs) operated in electrolyte are investigated as bio-sensors, since their output is quantitatively determined by the environment, and as signal processing units featuring frequency-specific response, enabling low-power on-board computation.
Since NOD timescales, charge carriers, and signal processing logic match those of the brain, NODs are the natural choice when tackling the convoluted task of interfacing neural tissue to establish bidirectional exchange of information. Nonetheless, the implementation of NODs in neuroelectronic interfaces designed for clinical applications comes with a number of hurdles which should be addressed, from both sides of the biotic/abiotic interface.
Here, we discuss some of these critical issues and we present strategies for overcoming them, with a focus on connection schemes, interrogation strategies, device geometry and material processing, tracing a vademecum for the development of NOD-based Neuroelectronics.
