In this modern era of wearable devices for monitoring patient, Wearable hyperthermia device plays an important role in the development of health care. A light wearable device can improve patient’s comfort and can be located close proximity to the body, thereby enhancing the energy deposition and reducing the power requirements. The device is primarily aimed at continuously tracking the skin temperature to indicate the onset of hyperthermia. The proposed prototype system provides an interactive user interface which is simple and efficient to monitor the body temperature and a sound alarm from buzzer in case of hyperthermia condition and hence, it will provide as a better detector over rise in temperature. The temperature status obtained will be transmitted to the monitor window via arduino and USB cable. Analysing body temperature will be useful in hospitals for bed ridden patients and sports persons. The final prototype would enhance the users to monitor their body temperature continuously and will help in identify the hyperthermia in its initial stage.
