Abstract
This paper describes a method for estimating blood pressure by using just one pulse wave sensor. Generally, to be able to measure blood pressure, cuffs are required for applying pressure, blood pressure measurement is time and effort consuming, and continuous measurements cannot be performed. If we are able to measure blood pressure without the use of cuff, we can solve these problems. However, features that obtained by pulse wave sensor are highly vulnerable to noise generated by various factors. In this paper, we evaluated the features using Taguchi's signal-to-noise ratio, and we extracted the features that are robust against noises. The effectiveness of the proposed method confirmed through the experiment of blood pressure estimation.
