The advent and subsequent explosive growth of hi-tech medical industry is one of the main features of the modern era. It is driven by the legitimate plea to apply smart healthcare environment for a broad range of working systems, entailing hospitals, schools, workshops, etc. In particular, smart healthcare offers a unique opportunity to optimise the interaction between the human and the medical system (equipment/tools and doctors) for diagnosis, monitoring and treatment measures, which certainly will decrease infections and disease’s transmissions. However, developing a reliable Internet of Things solution, to facilitate a seamless and flawless data transmission among smart assets, is an indispensable task to fully implement. Accordingly, the motivation for this paper is to develop an IoT technique for a non-invasive healthcare system to enable vast collecting and analysis of human vital data via a computer vision technique in order to reduce infections. In particular, concurrent IoT communication was designed for a mesh of three nodes, entailing a sensing node for heartbeat measurement, a vital data visualising node and a broker node. ... mehrThis was developed to guarantee a real-time visualisation of the vital data of the human/patient and it was enriched by an offline visualisation and online cloud visualisation via the broker node. Furthermore, an embedded software architecture was developed that offers a reliable solution to minimise communication latency and provides real-time response to acquired information. Also, the software design is applicable to easily interface with newly added nodes in the future to increase the scale of IoT mesh.
