A Prototype of an RFID-Based Command Sleeve with Changeable Microcircuits

This this study presents the initial prototype of a command sleeve designed to assist in pre-determined daily tasks and communication of those who have co-morbidities in terms of both speech and motor skills. The command sleeve is based on passive RFID tag design featuring a magnetic microcircuit attachment mechanism, for quick change and customizable assistance in varying situations. The command sleeve has two embroidered dipole antennas and altogether four microcircuits with magnet mechanisms. Testing on a human body demonstrated read ranges of around 150 cm for all antenna and microcircuit combinations. The findings suggest that there is potential in integrating magnet-based changeable microcircuits to passive UHF RFID technology, despite possible challenges in tag performance, which will be the focus of the next study.
