Pen‐type pulse wave measurement system for detecting pathological changes in cardiac diseases

Abstract

In this study, we have developed a new pen‐type pulse wave measurement system to evaluate heart failure treatment based on cardiovascular information. In order to acquire minute pathological changes in diseases such as heart failure, the pen‐type pulse wave measurement system is equipped with a high‐resolution MEMS tactile sensor that achieves a displacement resolution of 0.4 μm and an input resolution of 50μN. This measurement system consists of a small sensor package, a pen‐type measurement system, and a glass sensor package to enable physicians to measure the radial artery of men and women of all ages in a minimally invasive, rapid, and precise manner. Realizing this measurement system, simple and precise pulse wave measurement by direct measurement and measurement of pulse wave characteristics for individual differences has been possible.
