ABSTRACT

One of the greatest achievements of the present scenario is the development of smartphones that connect to the Internet. A natural outcome of this would be to connect electronic devices to the Internet and look for possible benefits. Internet of Things (IoT) essentially comprises several objects interconnected through radio-frequency (RF) sensors and their monitoring by means of the Internet. It is about merging the linked devices with automated systems to gather data for analysis and to take actions. IoT has unfolded immense possibilities in the areas of health care and medicine. An ordinary medical device connected to the Internet can give invaluable additional data, which can lead to a far greater insight into the symptoms. If the same data is available to a health expert, then it would enable the patient to get superior treatment remotely. A new paradigm shift is happening with the advancement of nanotechnology. The Internet of Nano Things (IoNT) is not far off. Nanomedicine, along with IoNT, would change the very basis of investigating, curing, and preventing diseases. Forthcoming health care presumes to bank on e-health systems braced with the hypothesis of IoNT in order to evolve more customized, well-timed, and convenient as well as cost-effective investigation, medication, and tracking of health. The major concerns of the day are whether IoT can help control pandemics like COVID-19. This chapter aims to discuss the applications of IoT, challenges in overcoming health-care issues, and highlights the steps undertaken to uplift health care in India.
