1.1 Introduction
The Internet of things (IoT) is an emerging technology in the modern information age. In the healthcare sector, a considerable number of wearables have been innovated using various types of sensors. Scientific researchers and innovators have been experimenting with wearable sensors to promote remote monitoring and early diagnosis of chronic diseases. The primary use of these sensors is to record useful parameters of the body such as temperature, heart rate (BPM), and breath acetone. Sensors are also used for storing obtained data in the cloud and local data repositories for future decision-making processes. An IoT-based healthcare system primarily contains three components: (1) cloud computing, (2) IoT, and (3) Wireless Body Area Network (WBAN).
IoT is a collection of nodes with wireless sensors that are recognized by a unique identification number. This unique number enables the communication between computers and sensors in the network to gather and distribute information .
Devices connected to the Internet such as implants, wearables, sensors, mHealth apps, and home monitoring tools that are rapidly increasing in number are more likely to link patients and healthcare providers in an unexpected way, utilizing big data innovatively.
The remote monitoring of health should be made trustworthy by incorporating WBAN, IoT, and cloud computing, which will be beneficial for the intelligent healthcare setting. Cloud computing also provides real-time data storage and processing for IoT devices like WBAN devices, which results in improved and cost-effective healthcare remote monitoring paradigms .
The key uses of an IoT healthcare system are improved clinical care, remote monitoring, and physiological and physical assistance for patients ().
Table 1.1
Key uses of an IoT-driven healthcare system
Clinical care | Patients who are hospitalized and require the close attention of doctors can be constantly monitored by using IoT-enabled devices. Various types of sensors can be used to collect comprehensive medical data on the status of patients in the cloud where it can be analyzed and stored before being wirelessly sent to caregivers for further analysis and review. This automated process can replace regular visits from a health professional to check patients vital signs . An IoT healthcare approach simultaneously improves the quality of care via continuous attention and minimizes the cost of care. |
Remote monitoring | Lack of effective health monitoring is a key challenge faced by patients globally. IoT, cloud computing, and WBAN devices provide a sustainable solution for this challenge by enabling remote monitoring for medical professionals. An IoT healthcare system can securely capture health data via numerous sensors, apply algorithms to analyze health data, and use cloud computing for information sharing with doctors in order to make appropriate recommendations. Remote monitoring provides effective and efficient preventive measures to enhance the quality of care provided for patients . |
Physiological and physical assistance | IoT healthcare devices largely emerged with the objective of providing assistance for patients suffering from physiological disabilities and physical infirmities. Various IoT devices and wearables have been innovated recently for these patients. As an example, people with ADHD (Attention-Deficit/Hyperactivity Disorder) benefit from IoT devices that are invented to help them develop their social skills and other activities of daily living . |
This chapter discusses recent IoT devices and wearables for various diseases in the human body by examining the benefits, algorithms used for data analysis, identified challenges, and countermeasures for each disease. In order to do this, scientific articles on the topics of innovation of wireless wearables and IoT healthcare devices published between 2016 and 2018 were sourced from the Institute of Electrical and Electronics Engineers (IEEE) database. Most of the reviewed articles have examined different technological aspects of IoT healthcare devices. Although many types of research have applied the theory of IoT to healthcare, it is hard to find work that provides different types of devices for various types of diseases. Also, the previous work concentrates more on the technological aspects of the invented devices, which is more beneficial for professionals with knowledge and experience in the fields of IT or Engineering. This chapter targets mainly healthcare professionals such as doctors, medical researchers, and medical equipment manufacturers. IoT is still an emerging theory in the world. The complexity of the previous research makes it difficult to be understood by ordinary people. This issue is eradicated in this chapter where the complexity is quite less when compared to other similar work and helps to take the concept of IoT in healthcare to ordinary people. At the same time, the work reviewed in this chapter is the most recent inventions, making way for new inventors to develop the techniques to create more advanced or new devices that will help control more diseases.
Analysis of the devices in this chapter is categorized by the types of diseases and the affected body systems. This analysis identifies which types of diseases or body systems benefit more from the use of IoT devices. This information provides opportunities for medical professionals to collaborate with inventors to create more devices concentrating on diseases and systems that have not been targeted in previous studies.
It is essential to address security and privacy issues in IoT, as these might hold back or slow down the development of IoT in various sectors. To increase the reliability and trustworthiness of IoT, these issues should be addressed. This chapter discusses the problems and drawbacks related to the implemented devices and proposes solutions to these challenges. It also discusses the benefits of each device thus making it favorable for future use.
