The results reveal the prospect of wireless stimulation with enhanced safety by eliminating contact between the implant and the brain, with optical telemetry for facilitated tracking.","journal":"IEEE Sensors Letters","year":2024,"id":465271,"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":4,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.952,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":507004,"name":"Diogo Moniz‐Garcia","orcid":"0000-0002-3654-3387","position":1,"is_corresponding":false},{"id":1153551,"name":"Daniel Gulick","orcid":"0000-0003-4692-7912","position":2,"is_corresponding":false},{"id":278684,"name":"Alfredo Quiñones‐Hinojosa","orcid":"0000-0003-4262-5968","position":3,"is_corresponding":false},{"id":1153553,"name":"Jennifer Blain Christen","orcid":"0000-0002-4980-5577","position":4,"is_corresponding":false},{"id":1153550,"name":"Ahmed Abed Benbuk","orcid":"0000-0001-9234-983X","position":0,"is_corresponding":true}],"reference_count":17,"raw_metadata":null,"created_at":"2026-07-19T02:04:46.201722Z","pmid":"38818033","pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
