Tactile-Transparent Wearable Sensor for Clinician-Friendly Pulse Wave Velocity Monitoring and Cardiovascular Risk Profiling.

ABSTRACT: Arterial stiffening is an independent risk factor for cardiovascular diseases, particularly affecting organs with low vascular resistance, such as the brain and kidneys. Pulse wave velocity (PWV) is the clinical gold standard for arterial stiffness assessment; however, conventional equipment requires complex setups and trained operators, limiting real-world and point-of-care monitoring. Here, we introduce a tactile-transparent wearable (TTW) sensor that preserves physicians' tactile pulse palpation abilities while providing quantitative cardiovascular risk assessment by integrating flexible Polydimethylsiloxane (PDMS) electrodes and ultrathin graphene oxide dielectric films. In a clinical study with 20 healthy volunteers (aged 22-60 years), the TTW sensor showed strong agreement with Doppl
