Abstract

here is provided an apparatus (100) for determining a blood pressure measurement for a subject (102)​. The apparatus (100) comprises a processor (104) configured to acquire, from a light sensor (106)​, measurements of an intensity of light (108) of a first wavelength range reflected from the skin (110) of the subject (102) for a range of forces at which the light sensor (106) is applied to the skin (110) of the subject (102)​. The processor (104) is also configured to analyze the acquired measurements of light intensity of the first wavelength range to identify an inflection point for the light intensity and determine a blood pressure measurement for the subject (102) based on the force at which the light sensor (106) is applied to the skin (110) at the identified inflection point.
