  1. NASA-JSC Update on RFID-enabled Sensing Work Raymond WagnerCCSDS Wireless Working Group Face-to-FaceNoordwijkerhout, NetherlandsMarch 31, 2014

  2. Recent Accomplishments • built prototype RFID-enabled sensor node: • built on JSC-developed modular instrumentation platform • uses Cypress C-G2 FRAM development board • implements DTN-like overlay to manage custody transfer of data to roaming interrogator • built prototype mobile RFID interrogator: • iRobot Create base provides (autonomous?) mobility • ThingMagic reader interrogates EPC Global C1-G2 RFID tags • RaspberryPi integrates components • Cypress board on modular instrumentation stack

  3. Recent Accomplishments (cont.) • tested interrogator/node combination • synthetic (counter) data generated at 0.5 Hz • interrogator piloted to make intermittent passes near node • all data (>1 hr.’s worth) successfully transferred • tested sensor interface • thermocouple interfaced to stack with 0.5 Hz sample rate • thermal events generated between interrogator passes and recovered/displayed upon interrogation • results to appear in WiSEE 2014 paper (?) • mobile RFID interrogator

  4. Ongoing/Forward Work • investigating a number of commercial RFID (EPC Global C1-G2) sensor technologies: • integrated sysetms (e.g., AMS, Phase IV, etc.) • RFID-enabled memories (e.g., Cypress, Fujitsu, Impinj) • focusing mainly on battery-assisted sensing • batteries provide power for MCU/sensors; RFID interrogator provides power for comm • months- to years-long operation targeted (depends on sample rate) • beginning to explore power-harvesting options (e.g., Powercast RF) • targeting developmental flight instrumentation (DFI) applications • ~500 μA active current (without sensors) • single-sensor sampling rates from 100 Hz – 1 kHz
