Abstract
A blood pressure measurement device includes a substrate, a protrusion portion, an image sensor, a first light source, a second light source, and a control and processing unit. A plurality of hollow portions is disposed within and enclosed by the protrusion portion. The first light source projects a first light toward the substrate. A finger presses the protrusion portion and the hollow portions, and the image sensor captures an image of a bright area. The control and processing unit determines whether the finger has enough pressure based on the bright area image. The second light source projects a second light toward the substrate, penetrating the substrate and the finger skin to be reflected by a blood vessel. The image sensor captures an image of a changed volume of the blood vessel, and the control and processing unit calculates the systolic or diastolic pressure.
