The practical application of flexible sensors in sound detection is significantly hindered by challenges such as information isolation, fragmentation, and low fidelity. To address these challenges, this work developed a composite hydrogel via one-pot method, employing polyvinyl alcohol (PVA) the first network, polyacrylic acid (PAA) second two-dimensional nanomaterials—reduced graphene oxide (rGO)—generated through redox reaction polydopamine (PDA) (GO) conductive fillers. uniformly distributed rGO within forms an efficient endowing material with high sensitivity (GF = 0.64), excellent conductivity (8.15 S m−1), rapid response time (350 ms), outstanding stability. synergistic interaction between PDA PAA modulates hydrogel’s adhesion (0.89 kPa), enabling conformal attachment to skin surfaces. designed rGO@PVA-PAA hydrogel-based sensor effectively monitors vibrations across diverse frequencies originating from five vocal cavities (head, nasal, oral, laryngeal, thoracic cavities) during singing. Integrated multi-position synchronization Bluetooth wireless sensing technologies, system achieves coordinated monitoring multiple cavities. Furthermore, demonstrates versatility detecting physiological signals, including electrocardiograms, subtle vibrations, multi-scale body movements, highlighting its broad applicability biomedical motion-sensing applications.
