Personalized healthcare is a term used to describe the process of recording and analyzing data about the particular patient’s clinical history and risk factors and providing personalized treatment and care. The term has gained popularity recently due to the increase in production of wearable sensor network devices in the market. These wearable devices are also known as IoMT devices.

Internet of Medical Things or IoMT is popularly known as a collection of medical devices and/or applications that can link to healthcare information technology systems using networking technologies (Al-Turjman et al., 2020). It minimizes the need for extraneous hospital visits and the burden of the healthcare systems by connecting patients to their doctors and aiding the relay of a large amount of data over a secure network. The way healthcare is approached worldwide has changed radically with the expansion of the Internet of Medical Things or IoMT as it is commonly referred, owing to the growth of smart sensors and devices in the healthcare sector. The market includes smart appliances, namely, wearables and medical/vital monitors, strictly for healthcare purposes on the body, at the patient’s house, or in a community, or in clinics and hospitals, and real-time location, telehealth, and other services. Some examples of IoMT devices are discussed in Section 11.3. IoMT can be classified into various segments as listed below:
