{"doi":"10.1115/dmd2025-1071","title":"A Low-Cost Shear Wave System for Ex Vivo Regional Mechanical Characterization of Planar Soft Tissues","abstract":"Abstract Shear wave elastography is a rapidly growing technique to determine material properties of soft tissues. Many of the existing devices used to initiate wave excitation in tissues of interest involve a cost that is prohibitive for experiments. Our study designed and developed a comparatively low-cost actuator and driver system to generate shear waves in ex vivo tissue specimens on the benchtop, so as to expand the current capabilities and applications of wave propagation elastography. The device features a solenoid that creates a magnetic force on a magnet connected to the actuator arm, driving the shear motion. Out-of-plane motion is minimized by two ortho-planar springs. The motion resulting from the driver system was captured by high-speed video and was analyzed using digital image correlation (DIC). The device was tested on ex vivo porcine aortic wall. The calculated wave speed was compared to the expected wave-speed based on uniaxial characterization. While the wave speed in the axial direction was lower than the circumferential direction, as expected, the measured wave speed was lower than the predicted value for both tissue orientations.","journal":null,"year":2025,"id":567470,"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":0.9516,"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":1471835,"name":"Kayla Lehtola","orcid":null,"position":1,"is_corresponding":false},{"id":438411,"name":"Victor H.
