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 (15)

1. A method for monitoring ingestion of medicine comprising the steps of:

forming an antenna comprised of conductive material and said medicine;

forming a digestible radio frequency identification (RFID) tag comprised of at least one of said antennas;

ingesting said RFID tag;

activating said RFID tag with signals and power from an external transmitter;

transmitting signals from said RFID tag to an external receiver; and

monitoring a signal from said RFID tag for changes in said signal due to dissolution of said antenna;

wherein said conductive material comprises metal segments and said medicine binds together said segments of said antenna.

2. A method as in claim 1 wherein said segments are pre-stressed, whereby said segments are released upon dissolution of said antenna.

3. A medication for administration by mouth, comprising:

an antenna comprising said medication and conductive material; and

an RFID tag connected to said antenna,

whereby dissolution of said medication renders said antenna inoperable;

wherein said conductive material comprises conductive segments bound in contact by said medication.
