A cardiovascular monitoring system includes a sensor assembly and a controller. The sensor assembly includes a membrane enclosing a viscous fluid, a substrate immersed in the viscous fluid, and at least one strain gauge mounted with the substrate. The strain gauge is configured to detect bending of the substrate due to changes in capillary blood pressure of a person in contact with the membrane at less than 50 mmHg contact pressure and to output a signal indicative of the changes. The controller may be configured to output a change in mean arterial pressure of the person based on a profile of the signal that is associated with a heartbeat of the person. Also, the controller may be configured to output the mean arterial pressure based on a weight signal indicative of a weight of the person and the profile of the signal associated with the heartbeat.
