A key factor governing brain tissue deformation and the risk of mTBI is the rotational kinematics of the head. Instrumented mouthguards are a widely accepted method for measuring rotational head motions, owing to their robust sensor-skull coupling. However, wearing mouthguards is not feasible in all situations, especially for long-term data collection. Therefore, alternative wearable devices are needed. In this study, we present an improved design and data processing scheme fo","authors_text":"Alice Lux Fawzi, Alison Brooks, Anu Tripathi, Christian Franck, Haneesh Kesari, Peter Ferrazzano, Rika Carlsen, Sheila Turcsanyi, Sushant Malave, Traci Snedden, Yang Wan","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.SP","submitted_at":"2025-04-02T17:47:07Z","title":"Laboratory evaluation of a wearable instrumented headband for rotational head kinematics measurement"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2504.01939","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:b030bc590c82afe0be6af2a749b4266597ba19bca3ce51f9634605f212807913","target":"record","created_at":"2026-07-05T10:43:32Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"3198b03dea74a193f18f1a0437fff28adf2259e8c38d2f7ce2da4de5d7b1e069","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.SP","submitted_at":"2025-04-02T17:47:07Z","title_canon_sha256":"d3543ea4a4d51972df21ca3bcf375c96dc4ade50d2ac57480d53e29f852f3792"},"schema_version":"1.0","source":{"id":"2504.01939","kind":"arxiv","version":1}},"canonical_sha256":"7ae5c236de28e985ef78a1fc4d11a848dc416d42ee75ec421cfc1458164d0782","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7ae5c236de28e985ef78a1fc4d11a848dc416d42ee75ec421cfc1458164d0782","first_computed_at":"2026-07-05T10:43:32.042505Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:43:32.042505Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WMIf0TFte+1HplEqmu+HAYjOuji0PWdovVMT38NkFvr0IUnhRPprCMHxBhv3GsjOI6VIiCziCtZPiQjSwq+DAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T10:43:32.042958Z","signed_message":"canonical_sha256_bytes"},"source_id":"2504.01939","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b030bc590c82afe0be6af2a749b4266597ba19bca3ce51f9634605f212807913","sha256:cc54d8a672d4304ee811337fd0aa682ae73ee7285900908eca637080f7495bb0"],"state_sha256":"13bf6fa9110ceede86f1b25c1b3b5490916388e5b3b2937d2e084ab3ad1a3ef6"}
