{"doi":"10.1002/advs.202409063","title":"A Membrane Magnetoelastic Generator for Acoustic Energy Harvesting","abstract":"Abstract Acoustic waves are a type of energy propagation through a medium with a low energy density, which makes it challenging to be converted into electricity. Here, a membrane magnetoelastic generator is presented as a fundamentally new technology for acoustic energy harvesting that is centered on a coupling of magnetoelastic effect and electromagnetic induction. It is as thin as 400 µm, holds a skin‐alike modulus of 2.59 × 10 7 Pa, a low internal impedance of 137 Ω, and a high current density of 107 mA m⁻ 2 at a sound pressure level (SPL) of 95 dB. It can efficiently harvest acoustic energy to charge a 47 µF commercial capacitor to 2 V in 20 s. With an all‐in‐one‐body design, the membrane magnetoelastic generator shows stable electrical output against environmental moisture and particulates. Toward practical application, it is demonstrated to harvest acoustic energy from a vehicle stereo and use recycled energy to charge a smartphone. Its inherent water‐/dust‐proof features open new possibilities for acoustic energy harvesting from city buildings, highways, airplanes, and even battlefields.","journal":"Advanced Science","year":2025,"id":513311,"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":10,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9494,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"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":617852,"name":"Jing Xu","orcid":"0000-0003-3157-6902","position":1,"is_corresponding":false},{"id":819181,"name":"Xiao Wan","orcid":"0000-0002-8638-2702","position":2,"is_corresponding":false},{"id":1200686,"name":"Chrystal Duan","orcid":null,"position":3,"is_corresponding":false},{"id":617856,"name":"Jun Chen","orcid":"0000-0002-3439-0495","position":4,"is_corresponding":false},{"id":1199748,"name":"Ziyuan Che","orcid":"0000-0003-3709-439X","position":0,"is_corresponding":true}],"reference_count":42,"raw_metadata":null,"created_at":"2026-07-19T02:48:17.908238Z","pmid":"40278831","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":[]}
