The main concept of IoT (Internet of Things) in healthcare is that doctors can watch over patients from anywhere, even when they're not in the hospital. Wearable devices pick up lots of information, such as heart rate, blood pressure, oxygen levels, body temperature, and ECG readings that show the heart's electrical activity. All this data connects through networks and cloud services, which likely cuts costs in the long run and makes checking on patients easier. I suppose patients enjoy the sense of always being looked after. In this paper, we looked at various IoT systems, with a focus on sensors, how they share information, how they handle the data, and ways to keep things secure to prevent issues. From reviewing the studies, we noticed common trends, like the types of sensors that are often used. For the future, systems might become smarter and more dependable, and they could grow or expand more easily. This could be helpful for students or researchers who want to create medical gadgets.
