Abstract

A system for monitoring ingestion of medicine (21) comprises forming a digestible radio frequency identification (RFID) tag (10). The RFID tag is attached to the medicine. The RFID tag and medicine are ingested. A signal from the RFID tag is monitored.

Claims

1. A device to be imbedded in a body for monitoring wear or motion of a bone within the body, said device comprising:

at least one RFID tag having an antenna subject at least to mechanical wear upon movement of said bone, whereby failure of said antenna indicates wear or movement of the bone; and

RF signal blocking means for blocking external signals from reaching said tag, said blocking means being subject at least to mechanical wear upon movement of said bone, whereby failure of said blocking means enables said signals to activate said tag, thus indicating wear or movement of said bone.

2. A device according to claim 1, wherein said blocking means comprises first and second layers of RF blocking material on opposite sides of said tag.

3. A device according to claim 2 wherein said bone is part of a joint, further comprising a third layer of RF blocking material and a second RFID tag located between said first and third or said second and third layers, whereby wear or movement of opposing members of said joint may be monitored.
