Abstract
Heatstroke happens when the body’s thermoregulatory mechanisms fail and the core body temperature rises above 41.1℃. Heatstroke will even lead to permanent organ failure or even death if left untreated. The risk of suffering from long-term damage for senior citizens as well as children is 10 times higher. In equatorial countries just like Malaysia, the maximum temperature can rise to 37℃. Without proper ways to mitigate the heat waves, heatstroke might strike at any hour. Therefore, this project is about the development of a wearable heatstroke detection device. The sensors and microcontroller are soldered onto a printed circuit board whereas the prototype is 3D printed. Heatstroke has no direct causation which resulted in no commercial product being released in the current market. Thus, a fuzzy logic controller is used to identify the heatstroke risk level by analyzing several physiological and environmental parameters which correlate with the causation of heatstroke. The sensory data obtained from the wearable device are being uploaded to Firebase real-time database. An Android application is built which able to display the current and previous user data. Accuracy and performance tests were carried out. The wearable device had low mean absolute error and low mean percentage error for all sensors. The wearable device is aimed to prevent the occurrence of heatstroke when the users are exposed to extreme weather during outdoor activities.
