Abstract:
1. A method of sensing a subject's blood pressure pulse comprising: non-invasively sensing, with an array of pressure sensors in contact against a skin surface over an arterial vessel, an arterial blood pressure pulse of the subject's blood pressure in the arterial vessel through multiple pulse cycles of the subject's arterial blood pressure pulse; and selectively pressing against the arterial vessel, during the sensing of the arterial blood pressure pulse through the multiple pulse cycles of the subject's arterial blood pressure pulse, at the location of each of the sensors of the array via at least two probes aligned in series along the arterial vessel with each respective probe dynamically exerting a different external force against the arterial vessel to cause a local artificial increase in the sensed arterial blood pressure pulse, wherein selectively pressing against the arterial vessel comprises:
