{"doi":"10.1021/acsami.5c00480","title":"Thermoelectric Composites Based on Porous Laser-Induced Graphene and Ion Hydrogel","abstract":"Despite the rapid development of single-modal flexible sensors, there is an urgent need to develop self-powered multimodal flexible sensing devices to eliminate power constraints. This work reports stretchable thermoelectric composites based on porous laser-induced graphene foams and an ion hydrogel, aiming to create a self-powered sensor that can detect temperature changes and strain with high accuracy. The self-powered strain sensor based on 3D porous laser-induced graphene (LIG) foam exhibits a high maximum sensitivity of 105.9 for strain up to 30%, a low detection limit of 0.071%, and good stability over 5,000 cycles at 30% strain. With an increased Seebeck coefficient of -189.90 μV/K, the sensor can also detect temperatures in the range of -10-100 °C with a resolution of 0.1 °C. The thermoelectric power generation array with integrated units can achieve an output voltage of 104.18 mV for a temperature difference of 20 °C. By combining the electronic thermoelectric material LIG and the ionic thermoelectric material NKKC/PFF, the dual-parameter sensors demonstrate high potential in human health monitoring, smart storage, and bathroom systems. The reported thermoelectric composites can be further utilized in temperature-strain decoupled sensing for battery monitoring, smart garments, and medical applications.","journal":"ACS Applied Materials & Interfaces","year":2025,"id":510306,"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":21,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9522,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1367344,"name":"Houze Yang","orcid":null,"position":1,"is_corresponding":false},{"id":725251,"name":"Mingyang Xin","orcid":null,"position":2,"is_corresponding":false},{"id":620289,"name":"Zihan Wang","orcid":"0000-0003-4018-1603","position":3,"is_corresponding":false},{"id":1366508,"name":"Hongyu Zhang","orcid":"0000-0003-1172-3653","position":4,"is_corresponding":false},{"id":850625,"name":"Ankan Dutta","orcid":"0000-0002-7572-5431","position":5,"is_corresponding":false},{"id":242463,"name":"Huanyu Cheng","orcid":"0000-0001-6075-4208","position":6,"is_corresponding":false},{"id":620282,"name":"Li Yang","orcid":"0000-0001-6798-3177","position":7,"is_corresponding":false},{"id":1366507,"name":"Hui Zhang","orcid":"0000-0002-9014-2488","position":0,"is_corresponding":true}],"reference_count":59,"raw_metadata":null,"created_at":"2026-07-19T02:47:36.538276Z","pmid":"40139959","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":[]}
