Data from: Monitoring microvascular changes over time with a repositionable 3D ultrasonic capacitive micromachined row-column sensor

eHealth devices, including smartwatches and smart scales, have the
potential to transform healthcare by enabling continuous, real-time
monitoring of vital signs over extended periods. Existing technologies,
however, lack comprehensive monitoring of the microvascular network, which
is linked to conditions such as diabetes, hypertension, and small vessel
diseases. This study introduces a novel ultrasound approach using a
Capacitive Micromachined Ultrasound Transducers (CMUT) Row-Column Array
(RCA) for continuous, ultrasensitive 3D Doppler imaging of microvascular
changes such as hemodynamic variations or vascular remodeling. In vitro
tests and in vivo studies with healthy volunteers demonstrated the
sensor's ability to image the 3D microvascular network at high
resolution over different time scales with automatic registration, and to
detect microvascular changes with high sensitivity. Integrating this
technology into wearable devices could one day enhance understanding,
monitoring, and possibly early detection of microvascular-related health
conditions.
