Abstract
A device and method to obtain accurate blood pressure measurement without a cuff, using a plurality of PPG sensors, in a non-clinical setting; that is, without the measurement being administered by a medically trained person. Unique and novel elements make this possible by eliminating the confounding effects of gravity in cases where the lay user is not careful to position the device at a specific or consistent elevation relative to that of the heart.
