An Action RFID Sensing Method Based on Reed Switch

This paper presents a passive sensing method based on Radio-frequency identification (RFID) tag for precise detection of actions or states. The RFID sensing tag is a ring structure consisting of RFID tag, spring antenna and reed switch. By adding a certain threshold of magnetic field, the tag’s antenna will work as dipole antenna or loop antenna, which can induce differences on RFID tag parameters. Among them, received signal strength (RSS) and phase can be used to detect the state change of the tag. It can perform accurate action or state detection such as open box and bottle cap rotation. In the future, this method can be applied in the field of health and life monitoring or other interaction scene of human and object.
