Item tracking system with electronic tracking labels containing sensors

摘要

A tracking and monitoring system that uses “smart” tracking labels with printed label information on the top and electronics and sensors embedded in thin, flexible layers underneath. Labels may be used to track the location of items, and to monitor item parameters such as temperature, shock, weight, or tampering. Tracking labels may have communications interfaces to transmit label location and sensor data to a centralized server for monitoring and analysis; interfaces may include for example Bluetooth, Wi-Fi, cellular, or Amazon Sidewalk. Label location may be determined from an integrated GPS, by triangulation using received signals from cellular or other networks, or from the location of nearby connected devices. Labels may be battery powered and may use energy harvesting to obtain power from the environment. To conserve battery life, manufactured labels may be put into a hibernation state, and activated when they are placed on an item.
