Abstract
A method of estimating a peripheral blood pressure and a biological data measurement system are provided by which the magnitude of a blood pressure in a capillary or an arteriole at a periphery may be estimated in a simple and non-invasive manner. Acquiring a photoplethysmographic signal from a capillary or an arteriole at a periphery of a user who is a subject by using a photoplethysmographic sensor; and calculating a peripheral blood pressure index based on the steepness of the rising edge of the photoplethysmographic signal are performed at the biological data measurement system, the peripheral blood pressure index serving as an index of the magnitude of a blood pressure in the capillary or the arteriole at the periphery. The magnitude of the blood pressure in the capillary or the arteriole at the periphery is estimated based on the peripheral blood pressure index.
