Radio-Frequency (RF) Tags (29)
Problem: Provide small "tags" without battery power that can be used remotely to identify and track designated objects
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Controls & Measurements
PNNL Solution:
- Determined that RF tags can meet a range of important client needs
- Developed capability to read and write to numerous, co-located tags
- Developed tags capable of query and data exchange at 100 m ranges
- Developed tags to monitor and control unattended sensors and equipment
- R&D 100 Award winner in 2001
- FLC Award winner in 2002
Capabilities Employed to Meet Client Needs: Radio-frequency (RF) field theory for antenna design and field propagation; information theory for evaluation of read/write distance effects on data transfer rates; analog and digital electronics design; surface mount electronics development; prototype RF tag design, fabrication, and evaluation; lab testing; test planning and analysis; documentation of technical basis and results.
