This document mentions characteristics of portable devices that highlight their applicability in healthcare because they fundamentally allow monitoring outside hospital institutions and allow the prediction of health events. This writing is achieved with the review of updated information available in the world scientific literature. Additionally, the challenges and disadvantages associated with the implementation of wearable sensors are shown. The aim of the above is to highlight that portable devices improve medical care in a wide variety of environments, but are particularly useful for the remote management of pathologies.
