Recent Trends in Smart Health Care: Past, Present and Future

Abstract

Electronic gadgets, actuators, sensors, and software link every element of an active network. The Internet of Things is the name of this network (IoT). AI technology may help networks, sensors, and users create a large quantity of data by assisting in the collection of data and the development of applications. The combination of AI with IoT may advance fields including public safety, education, healthcare, energy, transportation, and other value-added services. Smart health care makes extensive use of the Internet of Things (IoT), notably in the areas of emergency services, intelligent computing, sensors, security, and remote monitoring. Data privacy, integrity, and freshness are just a few of the security issues that must be resolved in a smart hospital. Additionally, there are privacy risks for patients, data eavesdropping, data integrity, and unique identification. IoT technology may be used to monitor a patient's health as well as their data. A patient's status might be tracked remotely and in real time using the internet and other technologies. Additionally, it enables the early identification and treatment of diseases that pose a danger to life. Medical records may be gathered and statistical information on a patient's condition may be provided via an IoT-enabled gadget. <br><br>With the correct software, huge amounts of data may be handled quickly and without errors. As a consequence of these advancements, which strive to fulfil patients' unique requirements while simultaneously enhancing treatment effectiveness, modern medicine is on the verge of a renaissance. The essential technologies that underpin smart healthcare are briefly described, together with the successes and challenges they have faced, the current status of these technologies in important medical areas, and the possibilities for the future of smart healthcare. Sensors gather data, which is subsequently sent over the internet of things (IoT) to supercomputers and cloud computing for processing and analysis.
