{"doi":"10.31438/trf.hh2022.26","title":"A STRETCHABLE NEURAL INTERFACE FOR VAGUS NERVE STIMULATION: FABRICATION AND ELECTROCHEMICAL CHARACTERIZATION","abstract":"Soft, stretchable design can improve long-term stability of neural interface devices.Here we present our latest efforts to design, fabricate and evaluate stretchable thin-film cuff electrode devices for vagus nerve stimulation, which have Y-shaped kirigami microstructures.We fabricated stretchable Y-microstructured thinfilm cuff electrodes by using conventional photolithography and reactive ion etching.The monolithic device design enables easier transfer to a different substrate without having to use the traditional PDMS-stamp-based transfer printing technique.We then characterized the electrochemical properties of the electrode/electrolyte interface and evaluated the charge injection limits as stimulating neural electrodes.Although the microstructured electrodes show up to 3.68 times higher impedance than the Euclidean geometry electrode due to the reduced surface area, they show up to 2.13 times higher charge storage capacities and 12.1 % higher charge injection limits, which may be useful for a chronic neural interface.","journal":null,"year":2022,"id":314450,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9491,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":411820,"name":"Matthew Ward","orcid":"0000-0003-3214-4087","position":1,"is_corresponding":false},{"id":411824,"name":"John B.
