Healthcare technologies using IoT possess the ability to integrate different systems and generate inter-operable services. Applications of IoT in healthcare include tracking/monitoring, identification/authentication, sensing and data collection/sharing. Advancements in Artificial Intelligence (AI) couple intelligent decision making and reasoning algorithms with data from different sources enabling rapid processing and complex analysis of data. The market for IoT based healthcare systems is at infancy, but is growing at a rapid rate. Developments in continuous health monitoring devices and distributed health management including telemedicine are few outcomes of the approach of IoT. e-health technologies are directed to remote monitoring of patients providing out-patient care with ease by real-time data transfer and updation from connected devices. This review provides an insight to the pros and cons of IoT in healthcare technologies along its recent attempts, future scopes and challenges on its way.
