Nowadays, systemic circulatory diseases are still one of the biggest challenges for the medical community to improve. Despite of the ad- vances on diagnosis and treatments, the World Health Organization recognizes Ischemic Heart Disease as the principal cause of death for both sexes, at all ages and worldwide on a 2016's report. Accordingly, there is a growing interest on providing better tools for the characterization of the state of the circulatory system exploit- ing the new trends such as wearable technologies and internet of things on medical devices. The aim of this project was to develop a low power and wireless device for non-invasive measurements of the pulse pressure wave imple- menting a flexible sensor technology based on a piezoelectric material.
