Fever Smart is a smart patch thermometer that allows parents to remotely and continuously monitor their children's temperature from anywhere in the world using their smartphone. A parent places the small device underneath the child's armpit using a disposable patch. The device constantly measures the child's temperature and sends the data to a relay unit, which sits in the same room as the child. This relay unit then sends the data to the cloud, so parents can access the information from anywhere in the world via a smart device. Parents download the Fever Smart app onto their phone and use the app to track their children's health. They can set individual parameters for temperature thresholds: when the child's temperature exceeds the thresholds, parents receive alerts so they can take immediate medical action.
