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. For this scope, an analog front- end circuit for the signal condi- tioning, and a microcontroller for the digital and transmission system were designed and integrated with the sensor. The system was tested by recording the pulse wave at the radial arterial pulse and sending the data to a personal computer while monitoring single performances at each stage. In conclusion, the resulting prototype can accurate measure the pressure wave, digitalize it, and send it via Bluetooth, satisfying the design requirements. In addition, the design can serve as a model for a further develop that extends it functions, in which pulse wave analysis and processing is applied.
