Mobile and wearable sensors are increasingly becoming our everyday life in monitoring and controlling health, well-being and security. Our work presents the technological enablers and requirements for building a complete end-to-end energy-efficient system for improving and controlling safety issues for children in day-care centers and schools. We designed a proof-of-concept for a wearable sensor vest with integrated wireless charging that takes place in the ordinary repository for the vests, such as in a wardrobe or a coat rack, without requiring any specific actions from the user. The developed sensor vest provides information about the location and well-being of children, based on received signal strength indication (RSSI), global positioning system (GPS), accelerometer, and temperature sensors. Teachers and parents are able to receive alerts and notifications, e.g., when a child moves across a certain restricted outdoor or indoor area, through gateways that have connectivity to a server or cloud. Piloting and technological implementations are based on a participatory study conducted among children, teachers, and parents, to gain important knowledge and understanding about the real user needs and service system usability requirements. The vest is part of a larger framework to provide digital safety applications and services through various sensor devices.
