Health is characterized as a full state of physical, mental, and social well-being and not merely a lack of illness. Health is a fundamental element of people’s need for a better life. Unfortunately, the global health problem has created a dilemma because of certain factors, such as poor health services, the presence of large gaps between rural and urban areas, and physicians’ and nurses’ unavailability during the hardest time.
IoT is making objects internally connected in the recent decade and it has been considered as the next technological revolution. Smart health-monitoring mechanism, smart parking, smart home, smart city, smart climate, industrial sites, and agricultural fields are some of the applications of IoT. The most tremendous use of IoT is in healthcare management, which provides health and environment condition tracking facilities. IoT is nothing but linking computers to the internet, utilizing sensors and networks. These connected components can be used on devices for health monitoring. The used sensors then forward the information to distant locations like M2M, which are machinery for computers, machines for people, handheld devices, or smartphones. It is a simple, energy-efficient, much smarter, scalable, and interoperable way of tracking and optimizing care to any health problem. Nowadays, modern systems are providing a flexible interface, assistant devices, and mental health management to lead a smart life for human beings.
Heart rate and body temperature are the two most significant indicators for human health. Various methods exist to invasively and noninvasively assess the heart rate and body temperature. For the consumer, noninvasive approaches over a while have proven accurate and convenient.
Some important works have been done in the field of medical science using IoT to monitor patient’s health.
Tamilselvi, et al., developed a health monitoring system that can monitor basic symptoms of a patient like heart rate, percentage of oxygen saturation, body temperature, and eye movement in IoT network. For this purpose, the system used heartbeat, SpO2, temperature, and eye-blink sensors as capturing elements and Arduino-UNO as a processing device. The developed system was implemented but no specific performance measures are described for any patient. Acharya, et al., introduced a healthcare monitoring kit in IoT environment. The developed system monitored some basic parameters of human health like heartbeat, ECG, body temperature, and respiration. The major hardware components, which are used here, are pulse sensor, temperature sensor, BP sensor, ECG sensor, and raspberry pi. The data was collected from sensors and sent to raspberry pi for processing and again transmitted to the IoT network. The major drawback of the system is that no interfaces for data visualization are developed.
Banerjee, et al., proposed a pulse rate-detection system based on a noninvasive technique. The proposed system used plethysmography process and correspondingly displayed the output digitally that made it a real-time monitoring device. The method has proved reliable for patients, compared to other invasive techniques. Gregoski, et al., introduced a smartphone-based heart rate-monitoring system. The system used a mobile light and camera to track finger blood flow and calculated blood flow-based cardiac output.
The developed system is described as an integrated device that wirelessly transmits a person’s pulse to a computer, empowering people to test their heart rate by merely looking at their phones instead of using hands each time. This is an excellent design but it is not feasible if continuous heart monitoring is needed. Oresko, et al., mentioned a fully functional cardiovascular disease-sensing system for smartphones, identifying a tool that is developed to be the same, given sufficient time and monetary resources. The developed prototype only tracked coronary rhythm in real time, did not track heart rate over time, and could not detect any cardiovascular disease.
Trivedi, et al., suggested a mobile device-regulated Arduino-based health parameter surveillance framework. The collected sensor data, which was in analog form, was sent to the board of Arduino Uno. By the integrated analog to digital converter, the recorded analog values were converted into digital data. Bluetooth transmitted the physical qualities to the developed device. The Bluetooth device used a module not covering a wide area. Kumar, et al., developed an adaptive IoT safety-monitoring device. The configuration of the framework is separated into three layers, such as the control layer, the device layer, and the transport layer. A DS18B20 sensor was used for the measurement of body temperature in the control segment and a pulse sensor is used for the pulse measurement. The data was loaded from Arduino into the cloud through the Wi-Fi module and Ethernet shield on the transport layer. The framework layer finally collected the server details. However, Arduino Uno was used here, and hence, many sensors could not be treated properly. Desai, et al., developed a wireless sensor network (WSN) to track smart homes and heartbeat. Here, Spartan3 is used in parallel data processing with FPGA architecture. The MCU results are shown by an LCD, and all sensors are connected with a microcontroller. Nevertheless, all machine elements are not integrated in one unit.

The introduction of rapid and sustainable advanced digital technologies could pave a new way to alleviate the situation and provide better healthcare. With advancements in the field of semiconductors and communication technologies, new options are available for patient monitoring that would readily enhance the quality of healthcare and improve patient safety. Many research groups across the globe have developed technologies to remotely monitor ECG, pulse oximetry, and non-invasive measurement of hemodynamic parameters.
In addition, artificial intelligence and machine learning-powered clinical decision support systems would support the physicians in interpreting data from multiple parameters, and aid in an early indication of respiratory failure, internal bleeding, or onset of sepsis.
Future developments of patient monitor systems will be more focused on making the system more interoperable, intuitive, and capable of predictive analysis. Systems with options to add advanced and individual features based on patient needs will enhance patient safety and ensure precise care. Specificity in vital parameter measurement, providing options for wireless monitoring and explicit alarms, would enhance job satisfaction for the frontline healthcare staff, reduce noise pollution, optimize the detection of false alarms, and, then augment the quality of care provided to the patients.
Also, replacing the fixed-screen display with mobile tablets or using IoT technology would help the clinical experts monitor the patient’s health status remotely.
The advancement in machine learning, IoT, artificial intelligence, wearable technology, and communication fields will be the frontrunner in the development of the healthcare sector in the coming decade.
