СКАЧАТЬ and clinics and having reached to home segment as well. With every second, 127 IoT devices adding in the market, and by 2021, it is expected that 35 billion devices will be connected to web, and by 2026, this market will touch almost one trillion US dollars. There are virtual clinics and telehealth for remote monitoring of patients both in rural areas and even where immediate access to clinicians by severely sick patients is always needed like cardiac and obstetric care. There is personal emergency response system (PERS) becoming highly popular in case of chronic critical diseases and is life-saving. The paper covers latest technological advancements for the on-body segment like the consumer health wearables. The traditional approach in healthcare being more personalized and touch-based system is not replaceable for diagnosis. The old-age, chronically ill patients need remote monitoring and medial management services that ensure the nurses or local healthcare assistants connect to doctors in urban or super-speciality fields for better services. The conclusion indicates that there is already a steep rise in IoMT products, but there is still a huge potential for growth in the IoMT industry.

1.1 Introduction

Early diagnosis and timely management of diseases through technological interventions prevents long-term complications and mortalities. The critical diseases like heart disease and stroke are leading cause of various forms of disability and death across the world. The burden of disease is extremely high in both developed and developing countries and least developed countries (LDCs). One of the main difference lies is with technology embedded systems and usage of Internet of Things (IoT) in entire medical treatment plans and even used later for monitoring of patients. This incredible change in the medical industry has been established with application of technology and specifically IoT in healthcare. IoT is defined as “Sensors and actuators embedded in physical objects are linked through the wired and wireless networks” [1]. Infrastructure facilities, optimal resource utilization, quality of service delivery, regular monitoring, timeliness of reporting, and resource mobilization have strengthened healthcare systems. It is more interactive and quick responsive system which is necessary for medical services.

1.2 Historical Evolution of IoT to IoMT

      Kevin Ashton who worked for Procter & Gamble in the year 1999 attempted to invent new technology to apply in his work space which led to the idea of linking radio-frequency identification (RFID) to “IoT”. Hence, this game changer technology was also known as embedded internet or pervasive computing. The year 2000 marked the beginning of internet in industries and almost all enterprises for information storage and retrieval of data. However, the accuracy being a concern so human to things and things to things interaction became more popular gradually. So, this slow development until 2010 suddenly saw a boom after the Gartner report in 2011. According to them, IoT is the network of physical objects which comprise of embedded technology for communication and interact with their internal states or the external environment [2]. IoT has helped in generation and utilization of huge data for rapid data processing. IoT utilizes cloud computing–enabled applications like consumer file storage. For leading company, Compaq, it was start of annually 2 billion USD turnover to sell servers to internet providers [3].

Though few aspects are non-replaceable by any form technology, still, digital interventions have penetrated in almost every component of all industries. Like in cases of libraries where, conventionally, these are in physical form of services and infrastructure, but it is now replaced with digital data storage and sharing to remotely access the intellectual content by anyone, anytime [4].

      Healthcare has been traditionally more popular in its physical form of interaction between patient and nurses, pathologist, pharmacist, or clinicians. Hence, the emerging technology is transforming lives by replacing the human touch in partial mode in banking and financial markets, retail shopping, education, security systems, and many other sectors. Healthcare sector has seen massive change by reducing the number of visits to the hospital due to technological developments [5, 6]. In true sense, the leverage for power of IoT is to eliminate the burden of healthcare sector by enabling patients to connect with the medical facility providers by transferring their data in a secured embedded system.

      The internet has been rebranded and is now referred to as “the cloud”. The IoT device requires a unique identification enabled by the RFID. Device has sensors for monitoring various parameters and can send the data through a wired or wireless communication to the cloud where this data is stored and can be converted into information. The procession of the enormous amount of data continuously generated (Big Data) requires immense computing power which is available in the cloud servers.

      Now, with technological advancements, the medical devices are enabled to collect, analyze, and send data across the web using these advancements. They can now connect both digital and non-digital heart monitor like the heart monitor with patient beds directly to internet. Internet of Medical Things (IoMT) is going to bring a paradigm shift and will alter the future of healthcare by providing smart digital solutions with ease, comfort, availability, and accessibility of quality healthcare anywhere, anytime.

      Most of the healthcare professionals and hospitals are now using IoT devices to optimally use their resources. Almost 70% of such hospitals and organizations use patient monitoring and maintenance of patient records. Patient data record is to be kept safely but industry is not tamper-proof, and hence, data leakage is still an issue in case of IoT. But still, in IoMT, there is an upper hand in as it has smart solutions which include endpoint security, internal segmentation, standard policies, and practices to authenticate end users and real-time monitoring which safety measures to prevent data breaches.

      1.2.1 IoT and IoMT—Market Size

With half of the IoT market, IoMT constitutes the largest part IoT market. In 2017, IoT market was at $41 billion and expected to increase to $158 billion in 2022 with connected medical devices contributing to one-third of the market by 2022 [7]. The statistics indicate the gradual penetration of IoT technology. Almost 7 billion IoT devices were there in 2018, and in 2019, it jumped to 26.66 billion active IoT devices. Every second, 127 new IoT devices are connected to web, and by end of 2021, there will be almost 35 billion IoT devices installed worldwide. In terms of revenue generation for IoT market, the global spending on IoT in 2016 was $737 billion, and by 2021, it is expected to reach $124 billion, and only by 2026, it will reach $1.1 trillion. This indicates the enormity of IoT markets as global IoT healthcare market should reach 14 billion USD by 2024 [8].

      Electronic patient records and patient monitoring are the largest usage of IoT in the present situation. Security in usage of IoMT is a major challenge. IoMT has improved the efficiency of healthcare delivery while lowering the cost of delivery per patient along with rapid implementation, thereby saving time and further lowering costs. The major challenge in IoMT is non-standardization of devices being in various platforms and inability for devices of one manufacturer to communicate with software or hardware of another. Multiple platform results in inefficiency. New devices and software need capital in terms of development and Food and Drug Administration (FDA) approval. Data privacy and security are factors that are to be kept in mind during its development and implementation. But implementation of IoMT increases cost of healthcare for devices, apps, cloud storage, and security. Data bandwidth required for the Big Data generated continuously by IoMT devices strains internet networks.

1.3 Smart Wearable Technology

      The on-body segment or smart wearables can be broadly divided into consumer health wearables and medical- or clinical-grade wearables. Medicalgrade smart wearables are high quality and are FDA approved for use in hospital or home use. But recently, high-grade consumer wearables have taken on the quality of medical-grade wearables and have been validated in studies to be useful.
