Abstract
RFID devices can be powered by one or more sources of RF energy, including available RF energy. RFID devices can be utilized to measure data, or receive data transmitted to the RFID device, and can preferably store the data and transmit the data to an RFID reader or other data receiver. In some examples, RFID devices can include one or more sensors that can measure data. In other examples, RFID devices can receive data transmitted from a remote data gathering device. In some examples, the RFID devices also include data logging capabilities, and can store data that corresponds to one or more data readings.
