ABSTRACT
Many IoT-based healthcare systems are being used in the healthcare business to monitor or diagnose a patient’s condition. A wide range of technological advances has led to a rise in health concerns among people, including the use of mobile phones has an impact on the eyes and brain, X-ray equipment raises the risk of cancer among patients. Many industries and researchers have come up with low-cost, powerful smart gadgets as a result of the rise in the population and the spread of disease. IoT-based healthcare solutions are becoming more popular as a result of the rapid advancement in wireless communication technology. Biosignal sensors and devices’ dependability and resilience are critical to the implementation of an IoT-based healthcare system at the highest level. These biosignals are generated as a result of changes in the membrane potentials of cells and include a wealth of physiological information. To find abnormalities in humans, the deviations are compared to normal patterns. These biosignals require unique bio-compatible measuring techniques that have certain qualities, such as low noise exposure. Additional steps are needed to ensure worldwide access to information, 2including digitization, filtering, and processing of data signals. This chapter examines all of the important points of view and compares the importance and necessity of each in terms of healthcare IoT services, applications, and security. IoT-based healthcare systems are introduced in this chapter, along with security and other issues that must be addressed to ensure optimal resource usage.
