1. A wearable monitoring device configured to measure a pulse transit time when worn by a user, the monitoring device comprising:
a wearable fixture configured for securing the monitoring device to a limb of the user and including a first band and a second band which is disposed at a fixed distance from the first band along a longitudinal direction defined by the user's limb;
a first transducer array attached to the first band of the wearable fixture, the first transducer array comprising a plurality of independent transducer elements for transmitting and receiving ultrasound energy;
a second transducer array attached to the second band of the wearable fixture the second transducer array comprising a plurality of independent transducer elements for transmitting and receiving ultrasound energy;
wherein the first band and the second band are connected via a slidable connection and are configured to rotate relative to one another along the slidable connection and around the longitudinal direction; and
an electronics assembly operatively coupled to the first and second transducer arrays, the electronics assembly being configured to determine the pulse transit time between the first and second transducer arrays.
