Continuous vital signals monitoring has gained a huge relevance for disease prevention that afflict a large part of the world population, for this reason, the healthcare equipment should be easy-wear and convenient-operate. Nonintrusive and noninvasive detective methods are the basic requirement for the wearable medical devices, especially when the devices are used in sports applications or by the elderly for self-monitoring. The aim of this paper is to measure continuous arterial blood pressure (ABP) through a cuffless non-intrusive approach. The arterial blood pressure is an essential physiological parameter for health monitoring. Most blood pressure measurement devices determine the systolic and diastolic arterial blood pressure through the inflation and the deflation of a cuff.
