A group of engineers from the University of Pittsburgh has invented a system based on RFID technology, designed to track and control orthopedic implants, reports PhysOrg.com.

A distinctive feature of the system is the use of human tissue as a conductor of radio waves, since open space is usually used to transmit radio frequencies. This invention is called "Ortho-Tag". It consists of a wireless chip attached to the implant itself and a portable reader that allows doctors to obtain the necessary information about the artificial limb.

The RFID chip sensors allow doctors to monitor the condition of the tissues around the implant and evaluate its pressure on them, as well as measure the temperature and chemical balance of the tissues and prevent the harmful effects of harmful microorganisms.

The "Ortho-Tag" system can also contain information directly related to the characteristics of the implant, such as the model range  or manufacturer - useful information that is used to identify defective or faulty implants.

For people using orthopedic devices, engineers plan to release wallet-sized cards with attached RFID tags containing data about the person and the implant itself.
