The low-cost electronic labels may pave the way for keeping tabs on our health.
RFID tags are being explored as possible low-cost sensors which could monitor and improve human health.
Radio-frequency identification tags (RFID) are simple, electronic labels outfitted with a tiny chip and antenna.
These labels are used to track and monitor everything from payments to products in a supply chain, but it is hoped that their use can go far beyond the tracking of physical items.
The Auto-ID Lab at the Massachusetts Institute of Technology (MIT) believes that the chip’s functionality can be transformed with a new feature: sensors.
To demonstrate the idea, the team has created an ultra-high-frequency (UHF) RFID configuration which “senses spikes in glucose and wirelessly transmits this information.”
