Implantable RFID System Created for Orthopedic Devices

Researchers from the University of Pittsburgh recently developed a system called Ortho-Tag, which basically involves an RFID tag that affixes to patients orthopedic implants and thereby enabling sensors to track the device’s health within a patients body.

The tag transmits such information via UHF or HF RF signals that travel through human tissue to a reader placed against a patients skin. This allows for the tracking of conditions inside the body surrounding the implant, but also the stability of the device in the event of a recall, etc. The reader would capture the ID of the implant and sensor data and display the results on the screen, as well as capture data for the back-end system via Wi-Fi or a USB port, allowing physicians to be alerted when there is any signs of patient infection, before they start showing symptoms.

Although the system is still being tested, it is estimated that it will be commercially available in approximately a year. Learn more about the implantable RFID system here.
