Abstract
Systems and methods for performing inventory management. The methods comprise: measuring, by an Out Of Stock (“OOS”) sensor at a first time, a first collective weight of a plurality of items disposed thereon; measuring, by the OOS sensor at a second later time, a second collective weight of a plurality of items disposed thereon; using the first and second collective weights to determine if an item has been added to or removed from the OOS sensor; and wirelessly communicating, from the OOS sensor to a remote computing device, a notification that an item has been added to or removed from the OOS sensor such that stored inventory information is updated accordingly. The OOS sensor comprises a base layer having a planar cross-sectional profile and an array of weight measuring sensors (e.g., piezoresistive sensors).
