Biocompatible Iontrode Neurostimulator for Highly Stable Neuromodulation |
| 초록 |
With the development of implantable electronics, soft conductor based on conducting polymer and hydrogel becomes an emerging field that can substitute metal electrodes showing mechanical mismatch of neural interface. However, such electrodes undergo faradaic charge injection, thereby resulting in acidic byproducts and ion diffusion which cause cell damage and degradation of devices. Herein, we present biocompatible ionogel based electrode with ion diffusion barrier for neural stimulation with wide range of capacitive charge injection. The system consists of chitosan as biopolymer matrix and choline malate as ionic liquid, which is stable under high applied voltage due to their wide electrochemical window. Consequently, our novel design of biocompatible iontrode based neural interface will provide a guideline for next-generation implantable electronics. |
