Stretchable ultrasonic device to identify and capture arterial blood-pressure waveforms. The high-performance 1–3 composite with piezoelectric microrods embedded in an epoxy matrix suppresses shear vibration modes and improves ultrasonic penetration into the skin. The wearable device can monitor peripheral vessel hemodynamics at different locations, for example, to sites of the brachial, radial, femoral or dorsalis pedis arteries.
