Problems solved by technology

The inconvenience of the PTT method is that the correction must be performed for each individual for accurate measurements
Furthermore, since biosignals must be measured at two or more locations in order to measure pulse wave velocity, it is difficult to construct a compact device
On the other hand, the PWA method estimates blood pressure only by analyzing the pulse waveform, so it is susceptible to noise and has limitations in accurate blood pressure measurement

Embodiment Construction

[0061] In the following description, the same drawing reference numerals are used for the same elements even in different drawings. Matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of the exemplary embodiments. It is apparent, however, that the exemplary embodiments can be practiced without those specifically defined matters.

[0062] It should also be noted that in some alternative implementations, the functions / acts noted in the blocks may occur out of the order noted in the flowcharts. For example, two blocks shown in succession may, in fact, be executed substantially concurrently or the blocks may sometimes be executed in the reverse order, depending upon the functionality / acts involved.

[0063] As used herein, singular forms are intended to include plural forms unless the context clearly dictates otherwise. It will also be understood that the term "comprises" or "comprises", when used ...

Abstract

A biometric information measurement device according an aspect may comprise: a pulse wave sensor which has a contact surface formed in a convexly curved shape toward a subject contact surface to comeinto contact with a subject, and measures at least one pulse wave signal from the subject having been in contact with the contact surface; a force sensor arranged on the lower portion or the side surface of the pulse wave sensor so as to sense contact force between the subject and the pulse wave sensor; and a processor for estimating biometric information of the subject on the basis of the at least one measured pulse wave signal and the measured contact force.

Description

technical field [0001] The following description relates to devices and methods for measuring biological information. Background technique [0002] Compression cuff based methods are used for general blood pressure measurement. The pressurized cuff-based method is a discrete measurement method in which the cuff is used to tighten the blood vessel to maximum blood pressure and loosen to measure blood pressure. The pressurization cuff-based method is not easily applied to portable devices due to the configuration of a pressurization pump or the like. [0003] Recently, a blood pressure measurement device for measuring blood pressure using a non-pressurization cuffless method without using a cuff has been studied. For example, there are blood pressure measurement devices based on pulse transit time (PTT) and blood pressure measurement devices based on pulse wave analysis (PWA). The PTT method is inconvenient in that correction must be performed for each individual for accura...
