A team of researchers at Stanford University announced a micro RFID tag that can be implanted into cells, such as skin or cancer cells. Tags are about one-fifth the thickness of human hair. It is used in conjunction with a dedicated RFID tag reader to interpret data and monitor cell activity in real time.

In the future, micro RFID tags can also be interconnected with sensors to facilitate the development of advanced biomedical skills such as antibody detection and cancer cell damage.

At Cornell University in the United States, researchers have planned UHF RFID tags, which can not only monitor vital signs such as heart rate, breathing, and blood pressure, but also do not touch patients. The label can be placed in a medical wristband or sewn into clothing.

RFID readers communicate wirelessly with tags to monitor multiple patients simultaneously. Medical staff can accurately understand the characteristics of each patient's life system without touching the patient, saving time and energy.
