Introduction
e term Internet of ings (IoT) is a relatively recent term and refers to the new generation of the Internet that allows information exchange and understanding between different and interconnected devices. ese devices may be sensors, tools, various artificial intelligence tools, and others [1]. It is also a modern technical method that aims to connect the things represented by sensors and various devices and connect them to the Internet to transfer data between these devices without human intervention if these things are within the geographical scope of the Internet [2,3]. e phrase "Internet of ings" was coined in the late 1990s by businessman Kevin Ashton. He was one of the phrase members that connected things over the Internet; also, he first utilized this phrase in his presentation in 1999, and this term remained accompanying him ever since [4]. Only a few years ago, we started to see the true potential of the IoT, the concept of wireless Internet development became more prevalent, embedded sensors developed tremendously, and people started to understand the technology that could also be personal as a professional tool [5].
What distinguishes the IoT is that it allows the person to be free from the place, that is, the person can control the tools without having to be in a specific place to deal with a specific device [6]. It is noteworthy that the IoT lists below many of the daily things that can be integrated with it, and the principle of work is applied to them, such as industrial machines, wearable devices, and many others. It must be noted that the coming period of technological life will be buzzing with it as it is the best way to make life more efficient [7]. e domain of implementation of IoT technology is extremely big in daily life and has entered into several main areas and is among the most important of these areas that can be integrated with communications, health care, factories, companies, and education [7]. e applications of the IoT in the medical field are among the largest and most significant applications. IoT has decentralized healthcare services from healthcare institutions to lateralized sites such as homes and workplaces, making it one of the most widely used advancements in e-Health today. It can monitor patients remotely and record their conditions in electronic records, and it can also be applied in wearable systems to help control many healthy habits including patients' sleep patterns [8].
Furthermore, this domain is constantly confronted with significant interoperability issues. For example, the safe, secure, and successful sharing of clinical data between healthcare organizations or research institutes can offer significant operational challenges. Such clinical data exchanges necessitate extensive, trustworthy, and healthy engagement amongst the parties involved. e nature of clinical data, sensitivity, data-sharing agreements, processes, complex patient matching algorithms, ethical policies, and governing norms are all potential barriers in this process.
IoT technology works without the need for the intervention of the human factor; it works to communicate between more than one device or machine automatically and freely, or between a device and a person, and these devices have the freedom to exchange data and information and take action to act on it as well without asking for help or approval from the human factor. e last industrial revolution has been considered as the technology of the IoT. Examples of commercial utilize the IoT: agriculture with pinpoint accuracy [9], intelligent parking [10], and management of water usage [11]. In addition, much research into the usage of IoT for constructing intelligent systems has been performed in different fields such as grids that are intelligent [12], crash-avoiding cars [13], and monitoring structural health [14].
Despite the fact that the aforementioned sectors appear to be drastically different from healthcare, the research undertaken within them supports the viability of an IoTbased healthcare system. Existing systems in other disciplines have demonstrated that remote object monitoring, data collecting, and reporting can be accomplished. e entry of the IoT in the field of health is a golden opportunity and really important to meet the challenges of chronic diseases and also to prevent diseases before they occur. A patient's treatment by using IoT applications includes the use of built-in sensors and actuators. Invasive monitoring systems depend on the IoT aid in the continuous monitoring and tracking of a patient's physiological condition. Radio-frequency identification (RFID) technology was utilized to track the activity of medical practitioners and other healthcare providers washing their hands in one of Ohio's premier hospitals. e deployment of IoT-based technology helped enterprises minimize infection-related death tolls while also lowering financial losses [15,16]. e mechanisms of applying the IoT in the medical field differed from the development of healthcare systems and medical devices by reducing the duration of hospitalization, clinic visits, and death rates, which leads to obtaining the best clinical results [17]. e use of IoT in the development of medical devices meets the needs of a variety of healthcare fields. Figure 1 shows a variety of medical-related IoT-driven devices. e following section describes the methodology of this study in terms of study objectives and their importance.
In this study, we designed a smart device for people who use computers for long hours during the day, especially programmers, so as to keep their backbone straight. e device is installed on a person's backbone; if a person bends his backbone for more than two minutes, the person is alerted by vibration for half a second. e rest of this paper is organized as follows. In Section 2, system description is presented. en, in Section 3, the components of the system are analyzed and presented. In Section 4, system implementation is presented. After that, Section 5 represents the results. Finally, the conclusion is presented in Section 6.

Study Description
Many people whose work requires sitting, especially programmers, suffer from a curvature of the backbone because of their wrong sitting, and then, these people begin to feel pain in the neck area and between the shoulders, fatigue, and exhaustion in the event of any activity or work, and if they continue to sit wrong for a long period, it will cause a twist in the backbone [30]. erefore, many of these people resort to wearing back corset, which is used as a support tool to reduce the development of the situation for the worse. However, this corset has many negative effects because of which people use this corset less; the most important of it is as follows. (1) It works to stabilize the muscles (not moving).
(2) Wearing the corset for long periods (for more than two or three hours) leads to a weakening of muscle strength [31]. Figure 2 shows the picture of a medical corset brace [32].
In this study, in the absence of a real tool that contributes and urges the practice of correct sitting, the device that we designed depends on alerting people and reminding them to adjust their sitting. In addition, with the passage of time in which this device is used, it contributes to training on a correct sitting. During the period of design of this device, we made sure to use low-cost materials so that anyone in society can own this device and to benefit all people who suffer from frequent curvature of the spine.

The Components of the System
is system contains six pieces electronics: (i) Arduino UNO (Figure 3): it is considered as a microcontroller board consisting of a 16 MHz ceramic resonator, reset button, 6 analog inputs, 14 digital I/O pins, USB connection facilitation, a power Jack, and ICSP header [33]. To operate the system, we use a USB cable or battery or power it with an AC-to-DC adapter to connect it to a computer [33,34]. (ii) Flex sensor (Figure 4): it measures the amount of bending or deflection. It is installed on a specific surface, and bending the surface changes the resistance of the sensor element [35][36][37]. We need two from it. (iii) Vibration sensor (buzzer) ( Figure 5): it is an auditory signaling device that can be electromechanical, mechanical, or piezoelectric in nature [38,39]. We need two from it. (iv) Female-female jumper wires ( Figure 6): it is normally used to interconnect the components of an Arduino UNO with sensors [40]. (v) USB cable (Figure 7): it is used to connect the UNO with PC [41]. (vi) Breadboard ( Figure 8): it is a building block for electronics prototyping [42]. Figure 9 shows the design of our project. We used the fritzing program and download it (https://fritzing.org/ download/) to experimentally design and draw this project. Figure 10 shows the algorithm used to implement this system. -Smart Pill Dispenser [29] IoT Driven Devices

System Implementation
e first flex sensor is installed longitudinally and the vibration sensor is next to it, on the upper part of the spine, as shown by the orange arrow in Figure 9. e second flex sensor is installed longitudinally on the bottom of the spine and the second vibration sensor next to it, as shown by the green arrow in Figure 9, so that both flex sensors take consecutive readings of the areas to which they are installed. If the user bends his backbone, see Figure 11, the vibration sensor starts, which is giving a shake for half a second to warn the person that he must adjust his seat.

Results
To carry out this experiment, we used Arduino software to get these results and downloaded it from https://www. arduino.cc/en/guide/windows. Arduino is programmed based on successive readings of the flex sensor. e vibration sensors work based on the reading of flex sensors.
e Arduino is programmed according to the following two levels: (i) Level 1 (flex sensor reading<�13): alarm will work (ii) Level 2 (flex sensor reading � � 33): alarm will not work Figure 12 shows the output window of the serial monitor, which displays the alerts. In the beginning, the system displays the reading of flex sensors (in top and bottom). After that, if the reading of flex sensors is less than or equal to 13 that means the backbone is curved at 100 degrees, the vibration sensors are working for half second to remind the user of the device to adjust his sitting and shows "alarm working" message on the serial monitor, but if the reading of flex sensors is 33, this means the backbone is straight and the vibration sensors are not working.
According to Figure 12, for example,

Conclusion
Many people whose work requires sitting for long periods suffer from pain in the neck and spine. erefore, many of these people resort to wearing back corsets, which are used as a support tool to reduce the development of the situation for the worse. However, this corset has many negative effects, including that it stabilizes the muscles (not moving), and wearing it limits muscle function. In this study, a smart alert system is designed to alert the person through an alarm so that this design helps to train the person to sit correctly.
To bulid this devise, we needed to use two flex sensors, two vibration sensors, UNO, breadborad, and wires. Also, we have used Arduino software to program this devise. e most important features of this device are that it is easy to use and of low cost; the accurate reading of the bending sensors and giving the right alert to the user of this device helped us in the success of this device. is system is considered a prototype [32-43].
