Abstract

The present disclosure relates to methods, apparatus and sensor for measurement of cardiovascular quantities. In particular, a method for determining one or more cardiovascular quantities is disclosed, the method comprising determining the distension of a vessel enclosed by tissue having a skin surface, wherein determining the distension is based on a first sensor signal indicating capacitance variations between a first electrode and a second electrode; determining the vascular stiffness of the vessel; and determining the blood pressure based on the distension and the vascular stiffness of the vessel.
