YourPacifier is a smart soother that detects the humidity on a baby's lips, rehydrates him or her when required, and informs the infant's guardian if further action is required. The idea for the creation was born when one team member was carrying out public health research in Asia and the Pacific islands. He learned that many young children were being hospitalized for diarrhea-related dehydration, which is often caused by the rotavirus, and decided that a solution was needed. A sensor in the pacifier measures the hydration levels of the baby. If levels are dangerously low, the pacifier alerts an adult of the danger through a mobile app. At this stage, the app presents the user with three simple questions, and based on the answers given, advises the user to, for example, seek medical attention at a hospital. Additionally, YourPacifier collects data that can be shared with hospitals, making it a useful tool in identifying and analyzing epidemics in surrounding areas.
