Many patients who are suffering from diseases need some applications to have a comfortable environment that allows them to ask for help easily, and we can list some applications like Implantable Glucose Monitoring systems, Activity Trackers During Cancer Treatment, Heart Monitors with reporting, Medical Alert Systems, Ingestible Sensors, wearables to Fight Systems Depression, Connected Contact Lenses, Location Services, Remote Monitoring. Keywords – Ingestible Sensors; Connected Contact Sensors; Implantable Glucose. I. INTRODUCTION IoT in HealthCare is considered one of the most important topics in the Internet of Things Applications. We can notice that healthcare is needed in our community. The need for healthcare has become more popular nowadays due to the spreading of viruses and illnesses [24]. For instance, we can realize that COVID has affected our life. So, we need to have enhanced Internet of Things Applications based on healthcare to fight against COVID, and other viruses or illnesses [22]. Years ago, there wasn’t an Internet of things on HealthCare. So, the interactions between the patients and doctors were limited to visits and telecommunications. Fig.1. IoT Healthcare System Fig. 1. IoT Healthcare System Architecture Internet of things gave us the significant features to have a good healthcare system like remote monitoring so that monitoring is specifically focused on keeping the patients safe and healthy. With remote monitoring, patient interaction and satisfaction have been increased as communication with doctors has become much simpler. Moreover, this feature helps to reduce the length of hospital stay and prevents re- admissions. Information of Things has an impact on reducing healthcare costs and improving hospitalization outcomes piece of information that helps them follow the dosages for their medications through patients' mobile apps [23]. II. INTERNET OF THINGS APPLICATIONS IN HEALTHCARE Implantable Glucose Monitoring Systems, Activity Trackers During Cancer Treatment, Heart Monitors with Reporting, Medical Alert Systems, Ingestible Sensors, Wearables to Fight Depression, Connected Contact Lenses, Location Services, and Remote Monitoring are all just a few examples of Internet of Things Applications in HealthCare. Implantable Glucose Monitoring Systems in HealthCare provide good and unique benefits to patients. This application is aimed at diabetic patients because it provides them with sensors. When a patient's glucose levels go too low, the sensors send information to their phone, which records historical data for them. As a result, patients will understand that they may identify when they are most likely to be at risk. One of the Internet of Things applications centered on healthcare is Activity Trackers During Cancer Treatment. Activity Trackers are used to keep track of a patient's movements, fatigue levels, hunger, and other factors. Furthermore, the data collected from the tracker before and during hospitalization will alert healthcare providers to any changes that need to be made to the proposed hospitalization plan. One of the HealthCare- based apps is heart monitors with reporting. This app is intended to track heart rates and assess whether they have excessive blood pressure. When people have Arrhenius syndrome, wearable gadgets can warn healthcare. Heart monitors with Reporting is one of the applications based on HealthCare. This application is used to monitor heart rates, which can determine whether they have high blood pressure. The healthcare professionals can be told by the wearable devices whenever patients are experiencing Arrhenius, palpitations, strokes, or full-blown heart attacks. Medical Alert Systems is one of the internets of things healthcare applications. In the event of an emergency, it is utilized to notify family members or friends. For example, if a
