Abstract
Systems, apparatuses, devices, and methods for monitoring mobility aids are provided. An example apparatus includes a wheel attachment assembly, a motion sensor, and a transceiver. The wheel attachment assembly is configured to removably attach to a wheel of a mobility aid. The motion sensor is configured to measure rotation of the wheel attachment assembly. The transceiver is in electronic communication with the motion sensor and configured to transmit data based on measurements from the motion sensor. An example system includes a monitoring device and a stationary communication node. The monitoring device is configured to removably attach to a mobility aid and includes a transceiver and a motion sensor configured to measure motion of the monitoring device. The stationary communication node is configured to communicate with the monitoring device. An example method generates alerts based on data from an attachable monitoring device.
