A Continuous and Wearable Blood Pressure Measurement Device with MEMS 3-Axis Force Sensor Array

In this study, continuous and wearable blood pressure measurement devices with MEMS 3-axis force sensor array were developed. We developed prototype devices for verifying the principle and a product like device with limited function, but small, and good appearance. By applying 3-axis force sensor to the tonometry method, high precise measurement with a standard deviation of 4.2 mmHg was realized. Since we realized reduction of body motion noise, our device can continuously measure the blood pressure even if the subject moves somewhat during daily life.
