Sensor-enabled RFID Tags Extend Wireless Data-logging Beyond Identification
ams has announced next-generation sensor-enabled RFID tags offering breakthroughs for medical, automotive safety and other applications where temperature, physiological or environmental data is required. The new devices, the SL13A and SL900A enable a simple, low-cost implementation of a new class of wireless data-logging applications.
The SL13A is an ISO15693-compliant tag for use with near field communications (NFC-V) and high-frequency radio-frequency identification (HF RFID) readers. The SL900A is an EPC Gen 2 Class 3 tag for use with RFID readers. The devices include an on-board temperature sensor, an interface to an external sensor, and can operate in passive (batteryless) mode. In this mode, the tag harvests energy from a reader’s broadcast, using the power to read the temperature or data from an external sensor, and transmits the information back to the reader together with a unique ID. The data is time-stamped by the reader.
