Abstract. Pulse wave analysis of central aortic pressure waveform (CAP) allows a detailed follow-up of pathologies such ashypertension, coronary artery disease and diabetes. A wireless, portable and ergonomic device (uFISIO) was designed to performmorphological evaluations of carotid artery pressure (AP Car ), which is closely linked to CAP behavior. AP Car waveform wasacquired by the applanation tonometry technique and sent to a hub node of a local wireless network, in order to be processed in amobile device. The results were posteriorly transmitted to a central server, in virtue of the Internet of Things (IoT) concept. 3Dprinting technology was also used to develop the design. The device was tested in 6 young individuals, where AP Car morphologicalparameters such as form factor, augmentation index, characteristic times and temporal integrals were assessed by the mobileapplication. Waveforms were acquired, transmitted, processed and stored adequately, obtaining values in agreement with previouspublications. The device showed versatility and comfortability in its use for AP Car evaluation, as well as for the management of theresulting information. Future studies are required to determine its clinical applicability, especially in different age groups.
