Objectives: It is now the era of healthcare 3.0 and there is a growing interest in wellness care as a means to health management. Methods/Statistical Analysis: The system is not confined to specific locations or areas for it to sense and react to emergencies. The portable health monitoring system proposed in this study utilizes sensors embedded within the wearable devices to continuously measure the user’s health and promptly alert relevant authorities and caretakers in case of an emergency. The portable health monitoring system proposed in this study needs to notify relevant authorities of emergency situations regardless of the user’s location. Findings: In recent days even smartphones are being released that have embedded sensors much like wearable devices, however these are only meant to improve the convenience of the smartphones and should be differentiated from wearable devices that have been developed to fulfill specific purposes. The system proposed in this paper automatically checks the user’s health in real time, vibrating the device as feedback in case of warning or danger. When within communication distance with a repeater via Bluetooth or NFC tags the system automatically forwards the collected data so that the users do not have to do so manually. Wearable devices are computers in the form of watches, bracelets, clothes, glasses, etc. that users can freely wear on their person. With the smartphone market reaching saturation the market for wearable devices with various add-on sensor functions is now attracting attention. The system also allows multiple users to share a repeater so that their information can be shared and ranked between the users, ultimately prompting users to be proactive in taking care of their health. Application/Improvements: This system can also be used as a form of big data by collecting the health information data of the middle-aged and the elderly and the real time feedback will allow a proactive management of the users’ health.
