Organic Electrochemical Neurons for Neuromorphic Sensing and Perception

Neuromorphic bioelectronic devices hold great promise for localized and personalized sensing within the nervous system, but traditional silicon-based devices face limitations in bio-integration, energy efficiency, and complexity. This presentation explores the development of organic electrochemical neurons (OECNs), which leverage the rich ion-tunable charge transport dynamics of mixed ionic-electronic conducting polymers to mimic neuronal spiking behavior. These OECNs offer low-energy, high-frequency performance, enabling advanced signal processing, efficient edge detection, and effective closed-loop neural stimulation. This breakthrough paves the way for next-generation implantable bioelectronics and neuromorphic robotics.
