Abstract
Measuring blood pressure in real time using wearable sensors mounted directly on the patient’s body is promising tool for assessing the state of the cardiovascular system and signalling symptoms of cardiovascular diseases. To solve this problem, we developed a new type of wearable arterial blood pressure monitoring sensor. Constructively, this sensor can be embedded in a flexible bracelet for measuring the pressure in the underlying radial artery. Due to the very small measuring pads (less than 1 mm\(^{2}\)) and, consequently, the ability to accurately position the contact pad directly over the artery, it is possible to ensure high quality of blood pressure measurement. However, since the artery itself is generally not visible, the correct positioning of the sensor is a non-trivial problem. In the paper we propose the solution of the problem – the positioning based on monitoring the pulse wave signals using three channels from closely spaced pads of a three-chamber pneumatic sensor.
